Masked men robbed Kim Kardashian West at gunpoint in the early hours on Monday, leaving her tied up in the bathroom of her luxury residence in Paris and stealing millions of dollars’ worth of jewellery, police and her publicist said.

Five attackers, wearing ski masks and clothes with police marking, struck around 3 a.m. (0100 GMT) inside the exclusive apartment block where Kardashian was staying while attending Paris Fashion Week, a police source said.

They stole a box with 5-6 million euros’ (about R76.28m-R91.22m) worth of jewels and a ring worth about 4 million euros, the source said.

She was discovered – “badly shaken but physically unharmed,” according to her publicist. The news went viral and Kanye West, her husband who was performing in New York abruptly ended the performance.

Police were guarding the apartment block on Monday morning, a discreet building behind the city’s Madeleine church, with several secret entrances, often frequented by movie and music stars who pay up to 15,000 euros a night.

The armed robbery could add to worries about safety in Paris, hit by a series of attacks by Islamist militants last year.

Tourist numbers to what is traditionally the most visited city in the world, fell 6.4 percent in the first half of 2016 as many Asians and Americans stayed away.

“We worry about the image of Paris. This will be all over the news channels, imagine the negative publicity,” Nathalie Kosciusko-Morizet, head of the conservative opposition in Paris, told Europe 1 radio.
