Russell Brand postponed the remaining dates of a comedy tour on Monday, two days after British news agencies published an investigation in which several women accused him of sexual assault.
Mr. Brand was due to perform two shows this week as part of his “Bipolarization” tour in Britain.
But in a statement on Monday from the Theater Royal Windsor, which was due to host Mr. Brand on Tuesday, the comedian’s promoters said the remaining dates of the tour would not go ahead. “We don’t like doing it,” the statement added, “but we know you will understand.”
On Friday, Mr. Brand denied what he called “serious criminal allegations” against him in a video posted to his YouTube channel. The statement was released shortly before three British news outlets published an investigation in which four women accused him of sexual assault, including one accusation of rape.
“Amid this litany of astonishing, rather baroque attacks, are some very serious allegations that I absolutely refute,” Mr. Brand said in the video, adding that past sexual encounters had “always been consensual.”
Since two newspapers, the Times of London and the Sunday Times of London, and the television program Dispatches, published their joint investigation, several organizations associated with Mr. Brand have distanced themselves from the comedian and actor who played a starring in the 2008 romantic comedy “Forgetting Sarah Marshall” and a 2011 remake of the film “Arthur.”
On Monday, The Bookseller, a British publishing trade magazine, reported that Mr. Brand’s publisher, Bluebird, was suspending its work with the comedian. Bluebird was scheduled to release “Recovery: The Workbook,” a guide to overcoming addiction, on Dec. 28. Bluebird did not respond to a request for comment.
Later on Monday, London police said in a statement that they had “received a report of a sexual assault believed to have taken place in Soho, central London, in 2003.”
British police forces never confirm the identity of a person who is the subject of a complaint, but the statement was issued in response to inquiries about the journalistic investigation into Mr Brand.
Mr. Brand has not yet responded to this latest allegation. On Monday at noon EDT, the comedian was scheduled to host a live show on Rumble, a social network associated with conservative voices, but he didn’t show up at that time.
