A Florida woman has became the fourth in recent weeks to say Bill Cosby gave her pills that made her feel groggy then forced himself on her sexually.
Therese Serignese, now 57, said the television icon raped her in 1976 when she was 19 years old following a show in Las Vegas. She said she went backstage and when the two were alone, Cosby (right) gave her two pills and a glass of water, saying, "Take these."
"My next memory is clearly feeling drugged, being without my clothes, standing up," she said. "Bill Cosby was behind me, having sex with me."
Cosby spokesman David Brokaw did not respond to a request for comment. Cosby's lawyer, in a statement on Sunday, criticised previous "decades-old, discredited allegations", stating "the fact that they are being repeated does not make them true".
Cosby made no mention of the allegations during a benefit performance in the Bahamas for a women's service organisation.
He stuck to his routine, including stories about his childhood growing up in the projects of Philadelphia. There were few empty seats in the house and a few people gave him an ovation at the end of his set.
Dozens of Cosby's former television and comedy colleagues have refused to comment in recent days.
The allegations by Serignese and three others are similar:
l Barbara Bowman, an aspiring actress, said in a November 13 Washington Post column that she was 17 and blacked out after Cosby drugged her, waking up to find herself in panties and a man's T-shirt with the television icon looming over her. She said she was certain she was raped.
l Joan Tarshis on Monday said she was a 19-year-old who wanted to be a comedy writer when Cosby gave her a drink and forced her to perform oral sex on him.
l Janice Dickinson on Tuesday told Entertainment Tonight that Cosby had given her red wine and a pill when they were together in a Lake Tahoe, California, hotel room in 1982. Cosby's lawyer, Martin Singer, said in a letter Dickinson's charges were "false and outlandish".
In addition, Tamara Green wrote an opinion piece for Entertainment Tonight. In 2005, Green publicly claimed that she was drugged and Cosby attempted to assault her; Cosby's lawyers have previously denied they knew each other.
Serignese, whose claims Singer did not address, says after the alleged rape, she willingly stayed with Cosby in Las Vegas for some time but could not specify how long or whether the two had sex again during their time together. The two also maintained sporadic contact for years after the alleged rape.
