French police were still hunting on Tuesday for five people suspected of assaulting Kim Kardashian West in a private Paris residence before robbing her of more than $10 million worth of jewellery.

After forcing their way into the American celebrity's apartment, the robbers held her up at gunpoint and locked her in a bathroom before escaping on bicycles in the early hours of Monday. They stole a jewelry box and a ring.

Kardashian West, who was in the French capital to attend fashion week shows, has since returned to the U.S.

Paris prosecutors say police have yet to identify the suspects and declined to answer whether they had received help from the reality TV star's entourage. Kardashian West's bodyguard wasn't present when the incident happened.

News reports say she feared she was going to be raped, as chilling new details emerge from the break-in that left her tied up in the bathroom of a luxury Paris apartment as masked men stole millions of dollars worth of jewellery.

Kim had been asleep in just a robe early Monday when she heard the robbers barreling up the stairs of her two-story apartment behind La Madeleine church in the city's 8th arrondissement, TMZ reported.

She was halfway through dialling her bodyguard when her phone was snatched out of her hands. Meanwhile, her quick-thinking friend Simone Harouche sprung from her bed downstairs and locked herself in a bathroom, the website reported.

The fashion stylist and long-time friend of the Kardashians called Kim's personal bodyguard Pascal Duvier, who was out at the Arc nightclub with Kourtney and Kendall less than two miles away. 

Meanwhile, the 35-year-old reality star begged for her life, screaming that she had two children as five masked men dressed in clothes with police markings bound her wrists and ankles with zip ties and duct tape before leaving her in the bathtub.

Kim managed to squeeze her hands out of the wrist ties by 'wriggling her hands,' a source told People. Another source said she 'screamed from the balcony' after freeing herself, which is when her friend Harouche heard her.

Kim, who later told police she feared she was going to be raped, didn't understand the French-speaking robbers amidst the chaotic scene.
