Kardashian was staying at an apartment inside a luxury private mansion that can be rented out for days or weeks at a time.

The French Interior Ministry said five men threatened the mansion concierge with a weapon, handcuffed him and forced him to open the private apartment.

Two of the men were able to gain entry to Kardashian West's room, according to the Paris prosecutor's office, and a gun was held to her head.
