A top Brazil police official has called on Ryan Lochte and three other American swimmers to apologize after some of the athletes claimed they were victims of an armed robbery.
Civil Police Chief Fernando Veloso says the four men became rowdy while at a gas station early Sunday after a night of partying. He says they were inebriated, and broke down the door of a bathroom, a soap dispenser and a mirror.
Veloso told a Thursday news conference that "no robbery was committed against these athletes. They were not victims of the crimes they claimed." He said there was confusion because people at the gas station didn't speak English and the athletes didn't speak Portuguese.
Lochte had said he was with the other swimmers when they were robbed at gunpoint early Sunday in a taxi by men with a police badge as they returned to the athletes village from a party.
Veloso says the four should apologize because "Rio residents saw the name of their city sullied."
10:10 p.m.
Alba Torrens and Astou Ndour each scored 14 points as Spain defeated Serbia 68-54 Thursday and assured its first Olympic medal ever advancing to the women's basketball final.
Spain will play for the gold medal Saturday, but being guaranteed at least the silver sparked a postgame celebration. Spain, which missed the 2012 Olympics, will play either the U.S. or France. In group play, Spain lost by 40 to the heavily favored Americans.
The Spaniards were barely able to contain their excitement as the final minutes ticked off the clock, dancing and hugging before running onto the court to celebrate. They posed for group photos after the buzzer; about the only thing they didn't do was cut down the nets.
Spain had Serbia frustrated most the game. Late in the third quarter Sonja Petrovic's pass went off a teammate's hands out of bounds. Petrovic kicked the Rio 2016 boxes bordering the court along the baseline - smashing one into pieces.
8:35 p.m.
A law enforcement official is telling The Associated Press that two security guards pointed guns at Ryan Lochte and three other swimmers during a dispute at a gas station.
The change in the version of events came after police interviewed one of the security guards on Thursday. It further deepened the mystery of what truly happened inside the station and set off an international dispute.
The official, who has direct knowledge of the investigation, spoke on the condition of anonymity Thursday because he was not authorized to speak about an ongoing probe.
The official said the swimmers broke the bathroom door and the soap dispenser inside. Security footage from inside the station shows the swimmers vandalizing the bathroom.
The official said workers at the gas station went to see what the commotion was about. At that point, a security guard also came and confronted the swimmers, and pointed a gun. A second guard came behind him and pointed another gun.
Brazilian police previously said no gun was pointed at the swimmers.
8:10 p.m.
Serbia has stunned the top-ranked U.S. women's volleyball team that was chasing its first ever Olympic gold.
With star player Foluke Akinradewo injured early, the Americans came back from a 2-1 deficit to force a fifth set before falling 15-13.
Serbia won 20-25, 25-17, 25-21, 16-25, 15-13 on Thursday - handing the U.S. its first defeat in Rio.
Akinradewo's teammates took over after she hurt her left knee late in the opening set.
With two-time defending Olympic champion Brazil also ousted in a five-setter by China in the quarterfinals, Serbia will now face either the young Chinese squad led by former U.S. coach Jenny Lang Ping or the surprising Netherlands team, which is back in the Olympic volleyball competition for the first time in 20 years.
8:10 p.m.
Peter Burling and Blair Tuke capped a dominant four years of sailing by winning the medal race in the men's 49er class at the Rio Games to confirm the gold they'd clinched two days ago.
The Kiwis upgraded the silver they won at London in 2012.
Showing just how much better they are than the rest of the fleet, the Kiwis sailed a tactically perfect final race, leading the whole way. They put their arms around each other and clenched their fists in triumph just before crossing the line, and then capsized their boat in celebration.
Defending gold medalists Nathan Outteridge and Iain Jensen of Australia took the silver. They sail for Sweden's Artemis Racing in the America's Cup.
Bronze went to Germany's Erik Heil and Thomas Ploessel. They both jumped into the water in celebration, and tipped their boat over. Last year, Heil was treated for infections he blamed on the polluted water in Guanabara Bay.
7:45 p.m.
The International Canoe Federation says canoe sprint bronze medalist Serghei Tarnovschi of Moldova has been suspended after failing a pre-competition doping test.
The 19-year-old Tarnovschi placed third in the 1,000 meters canoe single final Tuesday and was due to compete in the 1,000 meters double on Friday with his older brother Oleg.
The ICF said he would "now no longer be eligible and will face provisional suspension" under anti-doping rules.
7:30 p.m.
Misaki Matsutomo and Ayaka Takahashi of Japan have won gold in women's badminton doubles against Denmark's Christinna Pedersen and Kamilla Rytter Juhl.
The Japanese battled back Thursday from a late deficit in the deciding game to win the match 2-1.
Carolina Marin of Spain earlier beat Li Xuerui, the defending Olympic champion from China, to advance to the gold medal singles match against P.V. Sindhu of India.
Marin is world No. 1 but her win is significant because China had been badminton's powerhouse, sweeping all five badminton gold medals at the 2012 London Games. Li's gold was a big part of that dominance. Li will play Japan's Nozomi Okuhara for bronze.
7:25 p.m.
Stacy Lewis made 11 birdies and was atop the leaderboard in women's golf after an 8-under 63 at Olympic Golf Course.
Lewis made so many birdies she lost count. She wasn't aware of her score until she signed her card. The American was at 9-under 133 after two rounds and had a one-shot lead over Britain's Charley Hull. Several players, such as Inbee Park, were still on the course.
Marcus Fraser had a 63 last week in the opening round for the men.
Lewis, however, had a double bogey in her round when she three-putted the 14th from 25 feet. That made her determined to get the shots back, and she did just that by closing with four birdies. On the final hole, a tee shot in the face of a bunker left her 199 yards away for her third shot. She hit a hybrid to 4 feet for a surprise birdie.
7:15 p.m.
Germany, winner of the last two men's field hockey finals, came away with the bronze medal in Rio after beating the Netherlands 4-3 in a shootout.
Goalkeeper Nicolas Jacobi saved the Netherlands' first attempt by Billy Bakker, and stole the ball away from Sander de Wijn to secure Germany's 10th men's field hockey medal, second only to India's 11.
Tobias Hauke, Mats Grambusch, Timm Herzbruch and Linus Butt scored for Germany in the shootout.
The only regulation goals of the match came in the third quarter. Jorrit Croon rounded the defense to the backline where he pushed the ball between Jacobi's legs, and Germany leveled with another superb solo effort by Martin Haner, on a run from 30 meters out.
Germany also beat the Dutch in the pool round, and in the 2012 London final.
First-time men's finalists, Argentina and Belgium, will play for gold later Thursday.
7:10 p.m.
Croatia has moved one step closer to a second straight gold medal in men's water polo.
Andro Buslje scored four goals, Marko Bijac made 10 saves on Thursday as Croatia advanced to the RioGames final with a 12-8 victory over Montenegro. It also beat Montenegro in the semifinals of the London Games.
It was the highest scoring game in Rio for Croatia, which was coming off a 10-6 victory over Brazil in the quarterfinals.
Montenegro got within two on two occasions down the stretch, but Andelo Setka responded each time for Croatia. Setka's power-play goal with 2:44 left made it 11-8.
Darko Brguljan and Aleksandar Ivovic had three goals apiece for Montenegro, which finished fourth in each of the previous two Olympics.
6:55 p.m.
Hannah Mills and Saskia Clark of Britain have won the medal in the women's 470 class at the Rio Games sailing regatta.
Mills and Clark clinched two days ago and needed simply to finish Thursday's medal race.
Annie Haeger and Briana Provancha of the United States jumped into an early lead in the medal race and were in silver medal position. But they dropped to sixth and then fouled the Japanese boat, dropping them to last place in the 10-boat race and out of the medals.
New Zealand's Jo Aleh and Polly Powrie, the 2012 gold medalists, rallied for the silver medal after two disqualifications in the preliminary series. Camille Lecointre and Hélène Defrance won the bronze.
6:45 p.m.
Alistair Brownlee of Britain successfully defended his gold medal in the men's triathlon Thursday, winning the race at cloudless Copacabana Beach on one of the stickiest days of the Rio Olympics.
He grabbed a British flag while trotting into the finish line, where he won in 1 hour, 45 minutes and 1 second.
His younger brother Jonathan, who took bronze in London four years ago, moved up to silver, finishing six seconds back. Henry Schoeman of South Africa won the bronze medal, running across 42 seconds after the two-time gold medal winner.
The brothers collapsed once across the finish line, then rolled over to embrace each other.
American Ben Kanute was right with the Brownlees at the front following both the one-loop ocean swim and the steep, hilly 24-mile bike ride. But halfway through the 6.2-mile run, the difficulty of the course caught up to him and he fell to 29th.
5:35 p.m.
A male weightlifter from Kyrgyzstan has become the first athlete at the Rio de Janeiro Olympics to be stripped of a medal after a positive doping test.
The Court of Arbitration for Sport says Izzat Artykov tested positive for strychnine after winning the bronze medal in the 69-kilogram division.
The court says he has been stripped of the medal and kicked out of the games.
CAS referred the case to the international weightlifting federation for possible further sanctions against Artykov, who could face a two-year ban from the sport.
Luis Javier Mosquera of Colombia is in line to be upgraded from fourth place to the bronze medal.
5:35 p.m.
Two-time world champion Kerron Clement finally has an Olympic gold medal in the 400-meter hurdles.
The 30-year-old American won the world titles in 2007 and '09, sandwiched around his Olympic silver medal in Beijing, but hadn't been back on the podium of a major championship until winning Thursday's final in a season-best 47.73 seconds.
Boniface Mucheru Tumuti took silver for Kenya, 0.05 behind, and Turkey's Cuban-born Yasmani Copello, the European champion, won bronze in 47.92.
Javier Culson, the 2012 Olympic bronze medalist from Puerto Rico, was disqualified for a false-start.
Four of the finishers produced national-record times, including Tumuti and Copello.
5:25 p.m.
Si Yajie of China has topped another round of Olympic diving in the women's 10-meter platform.
The 17-year-old totaled 389.30 points over five dives in the semifinal round Thursday, not far off her leading score in the preliminaries.
The scores don't carry over to the afternoon final, but Si will have the favorable last spot in the order after establishing herself as the clear favorite to win China's sixth gold in seven diving events at Rio.
Jessica Parratto of the United States posted the second-highest score at 367.00, followed by 15-year-old Ren Qian of China with 362.40.
The top 12 moved on the final. Parratto's teammate, Katrina Young, finished 13th.
5:17 p.m.
A Brazilian police official is telling The Associated Press that American swimmer Ryan Lochte fabricated a story about being robbed at gunpoint in Rio de Janeiro.
The official, who has direct knowledge of the investigation, spoke on the condition of anonymity because he was not authorized to speak about an ongoing probe.
He said that around 6 a.m. on Sunday, Lochte, along with fellow swimmers Jack Conger, Gunnar Bentz and Jimmy Feigen, stopped at a gas station in Barra da Tijuca, a suburb of Rio where many Olympic venues are located. One of the swimmers tried to open the door of an outside bathroom. It was locked.
The official says a few of the swimmers then pushed on the door and broke it. A security guard appeared and confronted them.
The official says the guard was armed with a pistol, but he never took it out or pointed it at the swimmers.
According to the official, the gas station manager then arrived. Using a customer to translate, the manager asked the swimmers to pay for the broken door. The official says after a discussion, they did pay him an unknown amount of money and left.
Police plan an afternoon news briefing on the incident. A message seeking comment was left with Lochte's attorney.
5.15 p.m.
The United States is seeking to be reinstated into the final of the 4x100 meters, claiming that Allyson Felix was bumped by a rival runner just ahead of a botched handover.
The U.S. team crossed the line well behind all other teams in their relay after Felix picked up the baton and handed it over to English Gardner. Replays showed how Felix lost balance just before the handover.
"I got bumped coming into the exchange zone and it completely threw me off balance," said Felix. "I tried to hold it together to get to English. Maybe if I had one more step I could've, but I was falling."
5:05 p.m.
Tyson Gay helped the U.S. men qualify fastest for the final of the men's 4x100-meter relay, only minutes after the American women's team dropped the baton in the heats.
The former 100- and 200-meter world champion was part of the American team that placed second at the London Games but was stripped of the medal because of his doping violation.
The Americans - with Justin Gatlin sitting out the heats - got the baton around in 37.65. Japan won the second heat in an Asian record 37.68 to qualify second fastest, shaving 0.14 off the regional mark China had set in the first heat.
Usain Bolt didn't run in the heats, but his Jamaican teammates qualified by placing second to Japan.
3:20 p.m.
Women's badminton has seen a major shift in power as Carolina Marin of Spain beat Li Xuerui, the defending Olympic champion from China.
Marin on Thursday won the first game of the semifinal match 21-14 then took the second 21-16. Marin will play for gold Friday against the winner of the other semifinal, either Japan's Nozomi Okuhara or P.V. Sindhu of India.
Marin is world No. 1 but her win is significant because China had been badminton's powerhouse, sweeping all five badminton gold medals at the 2012 London Games. Li's gold was a very big part of that dominance.
Rio has seen China's best hopes regularly bounced, including Wang Yihan, the women's silver medalist in London.
China had two shots at bronze Thursday.
The women's doubles bronze medal match saw South Korea's Jung Kyung-eun and Shin Seung-chan beat China's Tang Yuanting and Yu Tang.
Later, in men's doubles, China's Chai Biao and Hong Wei will play for bronze against Marcus Ellis and Chris Landridge of Britain.
In Thursday's women's doubles gold medal match Misaki Matsutomo and Ayaka Takahashi of Japan face Denmark's Christinna Pedersen and Kamilla Rytter Juhl.
3:15 p.m.
Three American Olympic swimmers planned to meet with Brazilian law enforcement Thursday to discuss a reported robbery targeting 12-time medalist Ryan Lochte and his teammates, a U.S. Olympic Committee official said.
USOC spokesperson Patrick Sandusky said Jack Conger and Gunnar Bentz were released by local authorities after being pulled from a flight at the Rio de Janeiro airport, with the understanding that discussions would continue amid uncertainty over what truly took place during a late outing the night Olympic swimming wrapped up at the Rio Games.
Fellow teammate Jimmy Feigen also plans to talk to officials, Sandusky said, as he navigates a judge's order that keeps him in Brazil. The order similarly called for Lochte's passport to be seized, but the star swimmer had already returned to the United States before authorities could enforce the decision.
A lawyer for Conger and Bentz said Thursday that they won't be allowed to leave Brazil until they provide testimony to investigators. The swimmers didn't speak to reporters as they left the airport, shuttled away by a black car waiting outside. They departed for an unspecified location in Brazil and had yet to testify, said attorney Sergio Viegas.

The British Olympic team says an athlete was robbed while returning to their accommodation in Rio de Janeiro.
The British Olympic Association was responding to a Guardian report that the unnamed athlete was held up at the gunpoint after a night out in Rio. The BOA declined to say if the incident was reported to police.
In a statement, the BOA said "we can confirm there has been an incident of theft involving a Team GB athlete returning to their accommodation. All members of our delegation, including the individual concerned, are accounted for, and are safe and well."
3:10 p.m.
The U.S. announced its Olympic 4x100 relay teams for the first round and there's no Justin Gatlin.
But don't read too much into the pairings for Thursday's race - teams don't always trot out their top lineup for the preliminary round. Gatlin didn't make it out of the 200-meter semifinal the night before because of a nagging ankle injury. The final is Friday.
The men's lineup: Mike Rodgers to Christian Coleman to Tyson Gay to Jarrion Lawson.
The women's lineup: Tianna Bartoletta - fresh off her gold in the long jump - to Allyson Felix to English Gardner to Morolake Akinosun.
2:55 p.m.
Defending Olympic champion Yuri Cheban of Ukraine has won the gold medal in the men's 200 meters canoe single.
Cheban beat Valentin Demyanenko of Azerbaijan in a sprint to the finish line.
But the biggest cheers at the Lagoa stadium erupted when it was announced that Brazil's Isaquias Queiroz got the bronze in a photo finish - his second medal at the Rio Olympics.
Cheban fell out of his canoe as he pushed himself past the finish line. Queiroz also ended up in the water in the finish area.
Earlier, Max Rendschmidt and Marcus Gross of Germany won gold in the in the men's 1,000 meters kayak double. Serbia's Marko Tomicevic and Milenko Zoric took the silver and Ken Wallace and Lachlan Tame of Australia the bronze.
12:10 p.m.
The reigning king of track is back in his kingdom, lining up at Rio's Olympic Stadium for what he hopes is his 8th gold medal.
The biggest drama about Usain Bolt in the 200 meter sprint Thursday may not be whether he wins, but whether he cracks the once-thought-untouchable 19-second barrier. The Jamaican sprinter already owns both the world record at 19.19 seconds, and Olympic record at 19.30.
His challengers include Canadian Andre De Grasse and LaShawn Merritt of the United States.
In other medal events, Kerron Clement of the United States and Jamaica's Annsert Whyte compete in the 400 meter hurdles while American Ashton Eaton is leading after the first day in the men's decathalon.
South Africa's Caster Semenya runs in the women's 800 meters while American runners are seeking gold in the women's 400 hurdles. Joe Kovacs of the United States is favored in the shot put, and the women will compete in javelin.
11 a.m.
The jeering is over — and Brazilian fans are once again embracing the nation's most talented striker.
Neymar scored two goals Wednesday — including the fastest one in Olympic history, just 15 seconds into the game — to lead Brazil to a 6-0 rout of Honduras in the semifinals and keep alive its hopes of winning Olympic soccer gold for the first time.
The 24-year-old is vital for Brazil at the Rio Olympics and has regained the trust of the fans after a struggling start. His brilliant display against Honduras, which included a penalty kick in injury time, helped Brazil reach Saturday's final against Germany.
After the game, a shirtless Neymar pumped his fists as the crowd at Maracana Stadium chanted his name.
Andre Gustavo Correa, a fan, says "this is the Neymar that we like to see on the field ... we need him to have a chance to win this gold!"
10:40 a.m.
Tianna Bartoletta has dubbed it the "awesome hour."
In a span of about 60 minutes Wednesday night, U.S. track and field women hauled in a bevy of medals.
Bartoletta and Brittney Reese went 1-2 in the Olympic long jump, Tori Bowie captured a bronze in the 200 meters and Brianna Rollins, Nia Ali and Kristi Castlin swept the medals in the Olympic 100-meter hurdles — a feat that's never been accomplished in that event.
The best part, they say, was realizing what their fellow Americans were up to and feeding off that excitement.
The United States entered the Olympic Stadium on Wednesday with 13 medals in track and field and left with a total of 19 — five gold, seven silver, seven bronze.
