Police in Los Angeles have opened an investigation into a woman's claims that the comedian Bill Cosby molested her when she was 15.
Judy Huth, who is now 55, met with detectives yesterday after filing a civil lawsuit against Cosby earlier in the week.
He is counter-suing her, saying she tried to extort money from him, and has described her claims as "absolutely false".
The BBC reports more than a dozen women have alleged the 77-year-old star drugged and sexually assaulted them.
Mr Cosby has never been charged with a crime, and his lawyers have denied many of the claims, which date back to the 1960s. But the accusations have led to a tour being called off and several TV projects being cancelled.
A Los Angeles Police Department spokeswoman confirmed an investigation had begun after Ms Huth saw detectives for 90 minutes.
LAPD chief Charlie Beck had said people making allegations of sexual abuse against Mr Cosby should speak with his officers, even if their claims were outside the statute of limitations for prosecutions.
In her legal action, Ms Huth claims Mr Cosby gave her alcohol and forced her to perform a sex act on him in a bedroom of the Playboy Mansion around 1974.
She is seeking unspecified damages for "psychological damage and mental anguish", which have only recently been linked to the incident.
Mr Cosby's court filing seeks legal fees of $33,000. It said a psychologist had not supplied relevant certification about the effects on Ms Huth and said she tried to sell her story to a newspaper 10 years ago.
