Socialite Paris Hilton called police on Tuesday after seeing a man wielding two large knives and banging on her windows, apparently trying to break into her Los Angeles home.

"So Scary, just got woken up to a guy trying to break into my house holding 2 big knifes. Cops are here arresting him," Hilton said in a Twitter message.

She also posted a photo of police outside her house and a man in handcuffs.

Police confirmed they had arrested a man in his 30s and booked him on suspicion of burglary. No injuries were reported and the man did not gain entry to the house.

Sources close to Hilton, 29, said the socialite saw the man on her security cameras and called police immediately. She did not know the man and it was unclear if she was specifically targeted, celebrity website TMZ reported.

Hilton's publicist later released a statement saying that "Paris is naturally shaken by the events but is unharmed and well. She is very thankful to her security team and the police for their swift and diligent response."

Hilton was later seen by news helicopter emerging from the back of her home wrapped only in what appeared to be a large towel or bedsheet.

Hilton, the great-granddaughter of Hilton hotels founder Conrad Hilton, has worked as a model, singer, actress, fashion designer and reality TV star. She runs a multimillion dollar business based on her name, including clothing lines, fragrances, wine, and red-carpet appearances.
