Paris Hilton's House is Robbed

A man wearing a hooded sweatshirt broke into Paris Hilton's home in Sherman Oaks, Calif., and reportedly made off with millions of dollars worth of jewels.

"At around 5 a.m. Friday, officers received a call from a security guard who reported that Paris Hilton's residence had been broken into," LAPD spokeswoman Julie Sohn tells PEOPLE.

"According to detectives, a man wearing a hooded sweatshirt and gloves forced entry through the front door, ransacked her bedroom, took unknown property and fled," Sohn added.

An estimated $2 million in jewelry was stolen, according to the L.A. Times, citing unnamed detectives investigating the case.

An investigation is ongoing and Hilton was not at home at the time of robbery, Sohn said.

Early Friday morning, Hilton was spotted dancing at Bar Delux in Hollywood along with Katy Perry and gossip blogger Perez Hilton. A rep for the heiress wasn't immediately available for comment.
