Last week, the couple confirmed the incident in a statement released by their publicist. “On behalf of Jason Bateman and Amanda Anka, we can confirm that the account of André Balazs’s outrageous and vile behavior on that night in London is factual,” the statement said. “His actions were dealt with at the time.”

Since transforming his industry with the Standard brand he created nearly two decades ago, Mr. Balazs, 60, has expertly navigated channels of celebrity, fashion and business in New York, Los Angeles and beyond. The son of Hungarian immigrants, he dated the actress Uma Thurman for years and also dated the television host Chelsea Handler. He turned the sleepy Chateau Marmont into a hangout for members of the hip Hollywood set, like Johnny Depp and the singer Florence Welch. He has bragged of employing Ivanka Trump as an intern one year when she was a student.

In recent weeks, though, as stories about alleged sexual misconduct by powerful men in business, the news media and in Hollywood have surfaced (most notably Harvey Weinstein), several women have come forward accusing Mr. Balazs of groping them.

The Times left repeated and detailed messages regarding these accusations with Mr. Balazs, his executive assistant and his personal publicist, Pierre Rougier. The messages were not returned. Attempts to reach Mr. Balazs through the general managers at his hotels were also unsuccessful.

Mr. Balazs stepped down as chairman of the Standard chain’s board in March to focus, he said then, on his luxury properties.
