Bill Cosby Rape Allegation: US police launch investigation into claims TV star molested 15-year-old

US police are to launch an investigation following allegations that Bill Cosby molested a woman when she was 15-years-old.

Judy Huth is the first of twenty women, who claim they were drugged and sexually assaulted by Cosby, to file a police report.

Ms Huth filed a civil suit against the TV star in which she alleges he drugged her and forced her to perform a sex act on him in a bedroom of the Playboy Mansion in LA in 1974.

The 55-year-old first met with two special victim unit detectives for a 90 minute meeting after which an investigation was opened by the LAPD.

Los Angeles police chief Charlie Beck had earlier stated that any sexual abuse allegations would be investigated if someone files a complaint.

"We don't turn people away because things are out of statute. You come to us, especially with a sexual allegation, and we will work with you. The remedies may be limited but it's important to recognise that in many cases going through the process for a victim is very therapeutic so we address these things seriously and it's not just because it's Mr Cosby."

Celebrity women's rights lawyer Gloria Allred, who is representing Ms Huth, said "We are going to provide any and all evidence that she has."

Mr Cosby's lawyers have dismissed Huth's claims.

His legal representative Martin Singer, has said that Ms Huth's accusations are "patently false" revealing that she attempted to sell her story to a tabloid newspaper a decade earlier.

She is accused of attempting to extort money from the comedian after her lawyer, Marc Strecker, first demanded $100,000 for Ms Huth to remain silent, then raised the demand to $250,000 as more women came forward accusing Cosby of sexual misconduct.

Court papers filed by Cosby's lawyers state: "Approximately 10 years ago, plaintiff Judith Huff unsuccessfully tried to get money from a tabloid by selling the same story about Bill Cosby that is the subject of this lawsuit. Knowing that since she disclosed her allegations to a media outlet 10 years ago, she cannot claim to have a repressed memory."

Several high profile women including former supermodel Janice Dickinson, actress Louisa Moritz and Hulk star Lou Ferrgigno's wife Carla, have come forward to accuse the 77-year-old star of committing acts of sexual abuse after allegedly drugging them.

Cosby has remained silent over the reports of historical abuse, which are alleged to have taken place in the 70s.

Meanwhile, it was reported that vandals have defaced Bill Cosby's star on the Hollywood Walk of Fame.

The word 'rapist' was scrawled over the star several times.
