Lost star Matthew Fox was detained by police in Cleveland, Ohio on Saturday night after allegedly assaulting a woman, according to TMZ, who broke the news. The incident occurred when Fox allegedly tried to get on a party bus that was parked outside a bar, even though he wasn’t one of the guests. When the female bus driver tried to block the actor from boarding the bus, he allegedly punched her in the breast and stomach area. She later told police she hit him back in the mouth, and believed she’d broken her hand in the incident. Fox was handcuffed by an off-duty police officer who happened to be at the scene and was later detained by Cleveland police, although he did not wind up being arrested. He was picked up by a friend in a taxi and escorted to his hotel.
