( CNN ) Bill Cosby 's lawyer has denied the latest sexual assault allegation against the comedian . Cosby was not in California on the day in 2008 when Chloe Goins alleges the comedian sexually assaulted her at a Playboy Mansion party , Martin Singer , Cosby 's lawyer , said Friday in a statement . `` On Wednesday , Chloe Goins and her attorney publicly accused Bill Cosby of assaulting Ms. Goins in 2008 at the 'Midsummer Night 's Party ' held at the Playboy Mansion in California , '' the statement said . `` The party took place on August 9 , 2008 . Mr. Cosby was in New York on that date . We will be providing documentary evidence to the appropriate authorities which conclusively establishes Mr. Cosby 's whereabouts on August 9 and for the preceding and succeeding days . '' Goins , now 24 , told her story to investigating officers of the Los Angeles Police Department on Wednesday . Like other women who have accused Cosby , Goins said she was drugged and woke up undressed , said her lawyer , Spencer Kuvin . More than 20 women have come forward with claims of sexual assault against the comedian . Many of the accusations date back decades . Kuvin issued his own statement in response to Singer 's statement , saying : . `` The press should be asking Mr. Singer if Mr. Cosby was at the mansion at 'any ' time during the summer of 2008 . If he has proof of his whereabouts during that entire summer then we would like to see it . If he is willing to prove it , then I can comment . Otherwise it is just a lawyer talking , which is not evidence . '' CNN 's Kristina Sgueglia and Jean Casarez contributed to this report .
