Jury hears Bill Cosby's apology for 2004 sexual encounter

Bill Cosby says he apologised to the family of the woman he is accused of drugging and assaulting only because her mother thought he was "a dirty old man", according to testimony read to the jury.

Cosby's explanation was contained in a deposition he gave over a decade ago as part of a lawsuit filed by Andrea Constand, the woman whose allegations resulted in the only criminal charges brought against the TV star.
