Actor under investigation for attacking woman in nightclub

Police in the US are investigating an assault charge against actor Emile Hirsch, after an incident on Sunday night.

The Into The Wild star was at a Sundance Film Festival after-party in Utah's TAO nightclub when he got into an altercation with a female film executive.

Police were called to the nightclub at around 3.30am and although no arrest was made, Emile was questioned by police until around 5am.

"Emile Hirsch got into a fight with an executive at Paramount at TAO Sundance," an insider told Us Weekly "and the executive was looking into pressing charges against Emile."

The woman reportedly asked security to call the police after the incident occurred. "Something happened between the movie exec and Emile, and she said she had been assaulted and asked security to call the police," the source told Page Six. "Emile didn’t leave the scene, and calmly waited for the police to arrive, and spoke with them until around 5 a.m., after which he went home with his friends."

Another source said that the incident was very out of character for Emile. "He’s a really nice guy. I can’t imagine he’d be involved in anything like this," said one friend.

29-year-old Emile is currently at Sundance to promote his new coming-of-age drama Ten Thousand Saints, which also stars Hailee Steinfeld.
