BOSTON (AP) — The lawyer for a woman who’s accused Bill Cosby of sexually abusing her at the Playboy Mansion when she was 15 says she’ll seek a second deposition of the comedian.

Lawyer Gloria Allred said Saturday that Cosby appeared for a deposition in Boston on Friday that lasted several hours. Allred represents Judy Huth, who claims Cosby forced her to perform a sex act on him in the 1970s.

Allred says Huth will be deposed on Thursday. She says a California judge will decide in December if the testimony will be made public.

Lawyers for the 78-year-old Cosby say Huth’s lawsuit is frivolous and that Huth’s former attorney attempted to extort Cosby.

Cosby also faces two other cases: a defamation lawsuit brought by three women who claim he abused them decades ago and a suit filed Tuesday by a model who alleges he drugged and sexually assaulted her.
