Actor Emile Hirsch was reportedly questioned by police over the weekend (24-25Jan15) after cops were called to a Sundance Film Festival party in Utah.

Officers were called to the Tao nightclub in Park City to investigate allegations of a bust-up involving a movie studio worker, and Hirsch is believed to have been among those quizzed in the early hours of Sunday morning (25Jan15).

A source tells New York Post gossip column Page Six, "Emile didn't leave the scene, and calmly waited for the police to arrive, and spoke with them until around 5am, after which he went home with his friends."

A spokesperson for Park City Police says, "We are still investigating the details of the case and can't provide any further information at this time."

The Into The Wild star was in Utah to promote his new movie Ten Thousand Saints at Robert Redford's film festival.
