Capri Anderson

Capri Anderson, the adult-film actress found in Charlie Sheen's Plaza Hotel room last month, says she's suing the actor over battery and false imprisonment.

Anderson plans to file a criminal complaint in New York, she said on Monday's Good Morning America.

Recounting the night's events, Anderson, 22, said she was hired only to escort the Two and a Half Men star to dinner, but later retreated to his hotel room, where Sheen lost control.

"He was, from the beginning of the night, very loud and he had no hesitations when it came to using derogatory language or cuss words," she told ABC News.

Anderson said she heard Sheen snorting in the room and yelling racial slurs.

"But it wasn't until he put his hands around my neck that I really thought to myself, you have gotten yourself in a bad, bad situation," she said.

She said she locked herself in the bathroom, fearing for her life, and called for help.

Sheen was found intoxicated by police in the trashed hotel room and voluntarily checked in himself into a hospital for psychiatric evaluation. His rep attributed the daylong hospitalization to an "adverse allergic reaction" to medication.

Anderson said she's taking action because she doesn't want to "stand down and be completely walked over."

"It's not right to hurt people. It's not right to scare people," she said. "It's not right to carry on with such disregard for the people around you."

Yale Galanter, Sheen's attorney, denied Anderson's allegations.

"Ms. Capri never made any allegation of wrongful conduct on the part of Mr. Sheen the night of the incident," he said in a statement. "She has posted on her website that she was 'fine' after the incident but if you wanted to see more of her enter the website for money. We will defend this lawsuit vigorously and will never pay her a dime. These allegations against Mr. Sheen are completely false, and are a blatant attempt to cash in on his celebrity."

Anderson's full interview will air on Nightline Monday at 11:35/10:35c on ABC.
