LAPD to Investigate All Bill Cosby Assault Claims, No Matter How Old

— -- Police will investigate new sexual assault claims against Bill Cosby, regardless of the year the alleged incidents occurred, Los Angeles Police Department Chief Charlie Beck said.

“No, we don’t turn people away because things are out of statute,” Beck said. “You come to us, especially with a sexual allegation, you know we will work with you.”

The police attention comes as Cosby launched a counter-offensive against Judy Huth, who claimed that Cosby forced her to perform a sex act in 1974 at the Playboy Mansion. Huth was 15 at the time. The alleged incident was never reported to police, Beck said.

Cosby filed a lawsuit Thursday alleging that Huth is lying – and that she only filed a lawsuit after unsuccessfully trying to extort money from him. Additionally, according to Cosby’s lawsuit, Huth tried to “unsuccessfully tried to sell her story to the tabloids nearly a decade ago.”

The documents claim that Huth's story falls apart when she alleges that she and the comedian "engaged in a drinking game" in which they "both consumed three beers." Cosby’s attorney, Marty Singer, states in the suit, "It is a well-known, and easily verifiable, that Mr. Cosby is a life-long non-drinker."

Cosby is seeking monetary damages from Huth and her attorney.

Huth is among at least 18 women to come forward with similar claims against the 77-year-old Cosby in recent weeks. Cosby has never been criminally charged stemming from any of the sex-abuse allegations, many of which date back to the 1970s and 1980s.

Huth’s attorney has not responded to ABC News’ requests for comment about Cosby’s lawsuit.

Cosby’s representatives have also not commented on this week’s legal filings. But in a statement released last month, Singer called the recent allegations against Cosby “unsubstantiated, fantastical stories.”

Cosby used Twitter Wednesday to thank two of his supporters, Whoopi Goldberg and Jill Scott.

Fallout from the accusations continues for Cosby, with upcoming projects scuttled and re-runs from his popular programs pulled from television networks. The Navy announced Thursday that it was revoking Cosby’s title of honorary chief petty officer, saying allegations of sexual abuse against the comedian are serious and conflict with the Navy’s core values.
