Simon Cowell hid in his closet when an intruder broke into his home
Leanne Zaloumis was reportedly found in the bathroom of the music mogul`s London house with half a brick above her head and her hands drenched in blood in March and the `X Factor` boss admitted he was terrified by the incident.
He said: "I ended up hiding in one of my wardrobe closets until the police found her. That was a little spooky."
Simon was especially creeped out when he discovered she had copied the serial killer from the movie `Seven` by writing `Help me` on his wall in blood.
He explained to In Touch Weekly magazine: "A week later, I watched the movie `Seven` and serial killer did exactly the same thing."
After hearing a "loud bang" when the intruder crashed through the window when he was watching television in his home, Simon alerted his staff, who in turn called Scotland Yard and sent a squad of armed officers to the property.
Zaloumis was then found hiding on a shelf seven feet off the ground in a walk-in wardrobe.
The intruder appeared in court last month to be sentenced for the break-in.
She was handed a 12-month community order with a mental health requirement.
She has also been ordered to stay away from Simon under a restraining order, while she must also wear an electronic tag and adhere to a strict curfew.
