Los Angeles, CA (CNS) - Paris Hilton's house thief might be someone who is familiar with her place, according to the Los Angeles Police Department.

The police believes that, like what Hilton thought, the burglar knew how to access the heiress' collection of jewelry, OK magazine reports.

Hilton's Mulholland Estates place was robbed last month of nearly $2 million worth of jewelries and watches. Her bedroom was ransacked during the burglary, and police sources said security video showed a thief who was able to quickly find her collection.

The authorities also said that Hilton's jewelry collection was in a place that was not accessible for someone who simply searched the home. The thief entered through unlocked door some time between the late evening on December 19 and early morning of December 20.

Hilton herself expressed her belief that the burglar was a frenemy who has been in her house before.
