Five women have accused the comedian of sexual misconduct in a New York Times report
US comedian Louis CK has cancelled the premiere for his new film amid allegations of sexual misconduct made by five women.
Comedy actresses Dana Min Goodman and Julia Wolov are among the accusers.
After performing at the US Comedy Arts Festival in 2002, Louis CK invited them up to his hotel room after their show, The New York Times reports.
They told the newspaper they agreed because they wanted to celebrate and he was a comedian they admired.
As soon as they sat down, the comedian masturbated in front of them, they said.
Another actress, Abby Schachner, said the comedian masturbated while he was on the phone to her when she called to invite him to one of her shows.
Rebecca Corry, a comedian, claims the actor asked her if he could masturbate in front of her in 2005.
And a fifth woman, who wanted to remain anonymous, says he repeatedly asked her to watch him masturbate while she was working in production on The Chris Rock Show in the late 1990s, when CK was a writer and producer.
She went along with his request and he performed the act while sat in his desk chair, she said, with her in his office and colleagues just outside.
Ahead of the article's publication, the premiere for I Love You, Daddy was cancelled along with an appearance on The Late Show with Stephen Colbert, which was scheduled for Friday.
After publication, HBO told US media outlets that CK would not be participating in an upcoming benefit show, while they have also removed a number of his past projects from their on-demand service.
Louis CK's publicist Lewis Kay responded to the New York Times report by saying that the comedian "is not going to answer any questions".
In an email to Reuters, he said that Louis CK would issue a written statement "in the coming days".
It is the latest in a series of allegations against powerful figures in the US TV & film industry, including those against Kevin Spacey and Harvey Weinstein.
