The man who tried to break in to Paris Hilton's home this week has been charged with attempted residential burglary with a person present.

Earlier this week the man attempted to break into Paris Hilton's L.A. home but was greeted by Hilton's boyfriend who pulled a gun on the intruder.

TMZ reports that law enforcement sources confirmed that Hilton's boyfriend, Los Vegas nightclub owner, Cy Waits, grabbed a gun and checked out the situation. He had been alerted to the intruder by Hilton who heard noises coming from downstairs at about 6.30am on Tuesday.

Waits said that he spotted Nathan Parada, who has been charged, through the window. He was carrying two knives, a kitchen knife and a buck hunting knife.

Hilton Tweeted at 7.18am "So Scary, just got woken up to a guy trying to break into my house holding 2 big knifes. Cops are here arresting him." She also posted a picture of the arrest (see above).

Later Parada told the cops that he had planned to find Hilton's house. He purchased a Star Map on Hollywood Boulevard and followed it to her house. He is currently on a 5150 psychiatric hold in custody.

Hilton has now installed infrared technology to spot intruders. She has also hired two fulltime body guards to protect her.
