The veteran comedian has been found guilty in relation to a 2004 case.
In a retrial held today in Pennsylvania, comic Bill Cosby has been convicted of drugging and molesting former basketball player Andrea Constand.
The Cosby Show star was charged with assaulting Ms. Constand at his home in Philadelphia in 2004.
A jury of seven men and five women took 14 hours to find him guilty on all three counts of aggravated indecent assault.
At the start of the retrial it was revealed that Cosby had paid Ms. Constand almost $3.4m (£2.4m) in a civil settlement in 2006.
The lawyers of the 80-year-old comedian had called his victim a "con artist."
This was the second time Cosby had stood trial for the allegations, after an earlier jury failed to reach a verdict in June 2017.
Best known for starring in the 1980s TV series The Cosby Show, scores of women have accused Cosby of sexual assault in recent years, in allegations dating back to the mid-1960s, but statute of limitation laws mean that only one charge could be brought to trial.
Five of his other accusers testified against him during his trial.
