Kardashian Store 911 Call -- Some Creep Is Terrorizing Us

The Kardashians are so famous ... even their store has creepy fans -- this according to a recent 911 call ... in which a K-Klan clothing store employee begs for police help ... because some weirdo won't stop knocking on their door.

The call was placed on Monday by an employee of D-A-S-H in L.A. -- a clothing boutique owned by the Kardashian sisters -- but by the time police arrived at the scene, the creep had already taken off.

Sources tell TMZ, the mystery man in question had made a bunch of inappropriate comments that made the girls in the store feel uncomfortable. So when he left the store, they locked the doors behind him.

According to the 911 call, the man came back again and knocked persistently, demanding to be let in -- so one girl phoned police.

We're told the Kardashians are aware of the situation and are currently working with local authorities to track down the suspect. So far, no arrests have been made.
