NEW YORK — NBC has scrapped a Bill Cosby comedy that was under development and TV Land will stop airing reruns of “The Cosby Show,” moves that came a day after another woman came forward claiming the once-beloved comic had sexually assaulted her.

NBC spokesman Rebecca Marks said Wednesday the Cosby sitcom “is no longer under development.” A TV Land representative said the reruns will stop airing immediately for an indefinite time. “The Cosby Show” also was to have been part of a Thanksgiving sitcom marathon.

The NBC sitcom and “Cosby Show” reruns joined a Netflix Cosby standup comedy special, which was indefinitely postponed late Tuesday, as mounting evidence of Cosby’s faltering career. They occurred a day after model Janice Dickinson, in an interview with “Entertainment Tonight,” became the third woman in recent weeks to allege she’d been assaulted by Cosby.

The developments, which involve allegations that were widely reported a decade ago as well as new accusations, have gravely damaged the 77-year-old comedian’s reputation as America’s TV dad at a time when he was launching a comeback. A year ago, a standup special aired on Comedy Central and drew a hefty audience of 2 million viewers. His prospective new series was announced by NBC in January.

Cosby has never been charged in connection with any of the allegations. Former Pennsylvania prosecutor Bruce L. Castor Jr., who investigated a woman’s claims that Cosby had sexually assaulted her in 2004, said Wednesday he decided not to prosecute because he felt there was not enough evidence.

“I wrote my opinion in such a way as I thought conveyed to the whole world that I thought he had done it, he had just gotten away with it because of a lack of evidence,” the former district attorney said.
