LOS ANGELES (AP) - Los Angeles police opened an investigation on Friday into a woman's claims that Bill Cosby molested her when she was 15 years old, a department spokeswoman said.

The investigation was opened after Judy Huth, who is suing Cosby for sexual battery, met with Los Angeles police detectives for 90 minutes.

Los Angeles Police Officer Jane Kim said the department opened its investigation after the meeting.

Huth's civil suit claims Cosby forced her to perform a sex act on him in a bedroom of the Playboy Mansion around 1974 when she was underage.

Attorney Gloria Allred said Huth met with two special victim unit detectives Friday, three days after her lawsuit was filed.

“We are going to provide any and all evidence that she has," Allred said.

Huth did not take questions during a news conference.

Police did not give any additional details about the investigation. Police Chief Charlie Beck on Thursday urged potential victims of sex abuse by Cosby to speak with detectives, regardless of whether their claims were outside the statute of limitations.

Allred refused to comment on Huth's lawsuit, which was filed by a different firm. Cosby's attorney, Martin Singer, accused Huth and another lawyer of extortion and said she attempted to sell her story to a tabloid a decade earlier.

Singer's filing states the other attorney, Marc Strecker, first demanded $100,000 for Huth to remain silent, then raised the demand to $250,000 as more women came forward accusing Cosby of sexual misconduct.

Cosby has been accused by more than 15 women in recent weeks of sexual misconduct, ranging from incidents of groping to incidents of drugging and raping. He has never been charged with a crime, and his attorneys have denied many of the allegations.

Work crews on Friday were forced to clean up Cosby's star on the Hollywood Walk of Fame after someone wrote “Rapist" on it three times.
