US comedian Bill Cosby has been found guilty of three counts of sexual assault, each of which carries a potential 10 years in prison.
The actor, 80, has been on trial for drugging and assaulting ex-basketball player Andrea Constand in 2004.
Cosby, the first major black actor on primetime TV, will remain out of jail until he is sentenced, the judge ruled.
He unleashed an expletive-filled rant after the verdict, as prosecutors argued he should be denied bail.
It was the second time the actor had stood trial for the allegations, after an earlier jury failed to reach a verdict in June 2017.
At the start of the retrial in Pennsylvania it was revealed that Cosby had paid Ms Constand almost $3.4m (£2.4m) in a civil settlement in 2006.
Cosby is best known for starring in the 1980s TV series The Cosby Show.
Around 60 women over five decades have publicly accused the Emmy award-winning actor of being a sexual predator. But statute of limitation laws mean that only one charge has been brought to trial.
Some of his accusers were present in court, and cried as the guilty verdict was returned.
Cosby’s lawyer insisted “the fight is not over”, adding that he believes Cosby is innocent.
When the attack took place, Ms Constand was working as director of operations for the women’s basketball team at Temple University, Philadelphia.
She told the court she had gone to the home of her then friend Cosby, to discuss her resignation.
She said he had given her three blue pills to “help take the edge off,” which she believed to be a natural remedy.
Minutes later, she was suffering double vision and quickly lost consciousness.
She awoke to find Cosby groping her breasts and penetrating her, she said, adding that the drugs made her physically unable to fight back.
Ms Constant reported the attack, but the district attorney refused to press charges. The case was reopened in 2015.
Judge Steven O’Neill allowed five of Cosby’s other accusers to serve as “prior bad acts” witnesses during the trial, as the prosecution sought to establish a pattern of misconduct.
Former US model Janice Dickinson was among those who testified, alleging that Cosby drugged and raped her at a hotel in 1982, when she was 27 years old.
“I wanted to hit him, wanted to punch him in the face,” Ms Dickinson, 63, told the courtroom in Norristown, Pennsylvania. “I felt anger, was humiliated, disgusted, ashamed.”
The former reality television star testified Mr Cosby offered her a blue pill that he said would help with discomfort from menstrual cramps.
“He smelled like cigars and espresso and his body odour,” she said. “I couldn’t move, I felt like I was rendered motionless.
“Here was America’s dad on top of me, happily married man with five children and how very, very wrong it was,” she said.
The case against Cosby was one of the first celebrity assault trials conducted in the light of the #MeToo movement, which has raised awareness of alleged sexual misconduct by a number of powerful media figures.
