Hollywood actress Sandra Bullock locked herself in her bedroom and dialled 911 after she recently came face-to-face with an intruder in the hallway of her home.

Joshua Corbett, 39, is facing charges including residential burglary and stalking after he was arrested at the `Gravity` star's mansion in California.

Bullock was at home at the time of the incident, and now details about her ordeal have come to light, reports contactmusic.com.

Official police paperwork, obtained by tmz.com, reveals the Oscar winner got out of bed in the early hours of the morning after she heard a banging noise inside the house. She then came face-to-face with a man in the hallway, and ran back to her bedroom, locked the door and called for emergency services.

Bullock has since obtained a restraining order against Corbett, who is also facing a number of firearms charges after cops allegedly discovered a stash of weapons at his home.
