Three women have spoken publicly about their allegations that comedian Bill Cosby sexually abused and groped them decades ago.
The claims come a day after Mr Cosby was sued by a woman who said he molested her when she was a teenager in 1974.
The three women each sobbed while reading statements at a news conference organised by celebrity attorney Gloria Allred.
Ms Allred proposed that Mr Cosby should waive the statute of limitations that protects him from decades-old allegations from more than a dozen women.
Mr Cosby's attorney has called allegations against Mr Cosby as defamatory and was not immediately available for comment.
A woman, who gave her name only as Chelan, said that as a 17-year-old working at the Las Vegas Hilton in 1986, Mr Cosby drugged her, gave her alcohol and began to fondle her before she blacked out.
Beth Ferrier, who came forward with allegations against the 77-year-old last month, said the comedian gave her a coffee drink that caused her to lose consciousness and she later woke up with her bra undone in the back seat of her car.
Ms Ferrier said she was one of the several "Jane Does" in a 2005 civil lawsuit that made similar accusations against Mr Cosby and was later settled.
Another woman, Helen Hayes, accused Mr Cosby of groping her breast at a restaurant in 1973.
Mr Cosby is being sued by a woman who claims he sexually assaulted her at the Playboy mansion when she was 15.
Judy Huth, now 55, is suing the comedian in Los Angeles Superior Court, claiming sexual battery and infliction of emotional distress.
She says that she, at 15, and a friend, then 16, met Mr Cosby on a film set and that he invited them to meet at a tennis club the following week.
When they did, the suit alleges, Mr Cosby served the girls alcoholic beverages and they all played billiards.
"Under the terms of Cosby's game, plaintiff was required to consume a beer every time Cosby won a game," the suit claims.
After the two girls had "multiple alcoholic beverages", Mr Cosby allegedly told them he had a surprise for them "and led them to another house which turned out to be the Playboy Mansion".
In a room there, Mr Cosby allegedly "proceeded to sexually molest her", the suit claims.
Ms Huth alleges that she has sustained "psychological damage and mental anguish" throughout her life, but only recently discovered the problems were "caused by the sexual abuse perpetrated by Cosby".
Around 20 women have now accused the 77-year-old Emmy and Golden Globe winner of sexual assault and even rape, most from decades ago during Cosby's heyday.
The actor, known for playing a doting father on the popular Cosby Show in the 1980s and 1990s, has come under fire in recent weeks over claims made by many women.
"The new, never-before-heard claims from women who have come forward in the past two weeks with unsubstantiated, fantastical stories about things they say occurred 30, 40 or even 50 years ago have escalated far past the point of absurdity," his lawyer Martin Singer said.
