US reality television star Kim Kardashian was robbed at gunpoint at a luxury Paris residence in the 8th arrondissement by assailants disguised as police who made off with millions, mainly in jewellery, French authorities and her representative said Monday.
A spokesperson for Kardashian said she was "badly shaken but physically unharmed" after the assault, which occurred late on Sunday night at a residence near La Madeleine church.
SHe flew back to the US from Le Bourget airport to the north of Paris after being questioned by police.
Paris police said the items stolen were worth "several million euros" and were "mostly jewellery".
Reports in the French press claimed the star had two mobile phones stolen as well as a jewellery box with €6million worth of items in it and a €4million ring. It was not clear whether she had travelled with the jewellery or had been loaned it for the fashion show.
The spokesperson said "two armed masked men dressed as police officers" had entered Kardashian's residence and held her up at gunpoint.
Police sources told French media the robbers burst into the "hotel particulier" a private residence which the mega-rich can rent out and handcuffed the night guard.
He was forced at gun point to direct them to Kardashian's apartment. They then forced open the door, and held a gun to her head before tying her up and locking her in the bathroom, RTL radio and Europe1 radio claimed.
She eventually freed once the robbers had fled the scene, reportedly by bicycle.
Paris police authorities said: "Everything is being done to solve this case and arrest those responsible."
Specialist officers from BRB brigade, which deals with armed robberies are investigating.
On hearing the news, Kardashian's husband, rapper Kanye West, abruptly ended an appearance at a festival in New York, citing a "family emergency."
Kardashian, one of the most identifiable US celebrities, had made a series of high-profile appearances at Paris fashion week.
The 35-year-old had attended catwalk shows by Balenciaga and Givenchy on Sunday and had also appeared at a launch for Armenian-American jewellery designer Siran Manoukian.
The Los Angeles-born designer and socialite, a longtime friend of Kardashian, was launching her own clothing label Maison Siran.
On Monday, a gaggle of journalists and Kardashian fans gathered outside the red painted door of the luxury residence where Kardashian had been staying in the chic Madeleine district of Paris near the city's main department stores.
A waiter at a cafe opposite said: "Only stars stay there. Kanye West, Jay Z. Kim Kardashian has been there for a week, I have seen her coming and going.
While in Paris, Kardashian was last week approached by Vitalii Sediuk, who carries out pranks on stars. He was caught on video attempting to kiss her behind in an apparent social commentary.
Kardashian, who has two children with West, has been a fixture of US celebrity news for more than a decade after the leak of a sex tape and on the back of reality show "Keeping Up with the Kardashians."
Rap superstar West learned about the assault as he headlined a music festival in New York.
