Bill Cosby's sexual assault trial has started today with the beginning of the selection of the jury.

Up to 60 women have accused him of sexual misconduct, with some incidents dating back to the 60s.

Only one woman will have her allegations heard in court - a former friend of Cosby's - Andrea Constand, because of a law which limits the timeframe in which accusations can be made

Philadelphia Inquirer reporter Jeremy Roebuck told Rachel Smalley it'll be a complicated effort to select an unbiased jury.

He said the first 125 of the 3000 potential jurors were in court today.

"From the get go, one third of those 125 said that they had already formed an opinion one way or the other on Cosby's guilt or innocence."

Roebuck said Andrea Constand claims Cosby offered her some blue pills at his house in 2004 when she complained of a headache.

"And the next thing she knew, she was zoning out, zonked out, and she claims that in that period Cosby assaulted her."

Cosby won't take the stand during the trial.
