Nine fans have been arrested for violence following the Italian Cup final, which included clashes near the Colosseum, a window being broken on Roma's bus and an attack on a TV crew.

After Lazio beat Roma 1-0 in the derby Sunday, police had to intervene on a road leading to the Colosseum when opposing supporters clashed, leaving cars and bars damaged.

Also, some of Roma's hard-core "ultra" fans headed to the club's training facility on the outskirts of the city and threw eggs and rocks at the bus carrying the squad's players as it returned from the Stadio Olimpico.

Outside the stadium, journalists for the Mediaset TV network were attacked and robbed of equipment.

There were also brief clashes before the match and large caches of hidden weapons were confiscated.
