LONDON - A woman charged with breaking into the west London home of television entrepreneur Simon Cowell was remanded in custody Monday, according to Reuters.

Leanne Zaloumis, 29, was charged with trespassing on Saturday night after smashing Cowell's bathroom window and hiding in his $14-million London mansion's walk-in closet. After she was arrested, officers found blood marks in the bathroom.

Britain's ITN quoted the "X Factor" judge's spokesman Max Clifford as saying that Cowell heard a "loud bang" at around 10:30 p.m. local time (5:30 p.m. ET) on Saturday.

"Simon rushed upstairs to find out what was going on," Clifford said. "It came from the bathroom so he went in and there was a woman standing there holding a brick."

 Clifford said Cowell had described the incident as "like something from a horror movie."

"It was a very frightening experience for Simon," he added.

Cowell's security team detained the woman until police appeared, according to The Sun.

Citing sources, The Sun reported that the woman was believed to be an "over-zealous fan," and police said nothing had been taken.

Zaloumis is slated to return to court on June 12.
