Emile Hirsch is currently under police investigation for an alleged assault on a woman during the Sundance Film Festival in Park City, Utah, reports Us Weekly.

The woman, who is executive at Paramount Pictures, is flaming that the Into The Wild star, assaulted her at 3:30 AM at TAO nightclub on Sunday.

"Last night, Emile Hirsch got into a fight with an executive at Paramount at TAO Sundance … and the executive was looking into pressing charges against Emile this morning," a source told the mag.

The Park City Police Department gave a statement to Us, "We are still investigating the case and cannot provide details at this time."

Page Six first reported the story, which said that the police were first called to the scene at the time of the alleged incident but was not arrested. A source told the New York Post's gossip page, "Something happened between the movie exec and Emile, and she said she had been assaulted and asked security to call the police … 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. No arrests were made."

The actor, who is at the film fest to promote his new film Ten Thousand Saints, has a 14-month-old son.

Local authorities will submit an official report once the investigation is complete.
