NEW YORK — Bill Cosby’s upcoming appearance on CBS’ “Late Show with David Letterman” has been canceled amid a growing uproar over allegations that he sexually assaulted several women in past decades.

Cosby representative David Brokaw confirmed Friday night that Cosby would not appear as previously scheduled next Wednesday. He did not say why. A “Late Show” representative could not be reached for comment.

Another canceled booking, on “The Queen Latifah Show” on Oct. 30, was characterized by that show as a postponement granted at Cosby’s request.

Barbara Bowman, one of Cosby’s accusers, has recently leveled allegations of sexual assault by the comic in interviews and in a Washington Post online column, writing that “Cosby won my trust as a 17-year-old aspiring actress in 1985, brainwashed me into viewing him as a father figure, and then assaulted me multiple times.”

The standup comedian Hannibal Buress last month brought heat on Cosby at a performance in Philadelphia. His routine, during which he assailed Cosby as “a rapist,” was captured on video and posted online, gaining wide exposure.
