NORRISTOWN, PENNSYLVANIA (REUTERS) - Comedian Bill Cosby's pre-trial hearing continued into its second day on Wednesday (Dec 14) evening as prosecutors sought alleged victims of sexual assault to testify at an upcoming sexual assault trial next June.

Pennsylvania prosecutors want a "bandwagon" of unreliable accusers on parade at the trial, the comedian's defence lawyers said on Wednesday.

Lead prosecutor Kevin Steele countered, telling a state judge that the women can help prove that Cosby is a serial predator who engaged in a "lifetime of sexual assault".

Cosby, 79, faces sexual assault claims from about 50 women altogether, though the Pennsylvania case is the only criminal prosecution to result.

The actor, who once enjoyed a family-friendly image, has denied any wrongdoing.
