The woman who was driving the bus tried to block Fox from getting on board — at which point, he allegedly punched her in the breast and the “stomach area.”Fox was handcuffed by an off-duty officer — and was later detained by police.Fox was released without being formally arrested. An assault report was taken and the matter remains under investigation.We have not been able to reach Fox for comment. The woman PUNCHED BACK and struck Fox “in the mouth causing a cut on his lip.” The woman told police she may have broken her hand during the altercation. Fox was later released to a friend who put the actor into a taxi and accompanied him back to his hotel.
The woman who punched Matthew Fox in the face this weekend tells TMZ … she HAD to let her fists fly because the actor struck first and she needed to defend herself.

TMZ spoke with Heather Bormann who tells us she was driving a party bus for a private party Saturday night in Cleveland when Fox boarded the vehicle. Bormann claims she told Fox he wasn’t welcome on the bus but he was too drunk to understand. Bormann says, “He just kept staring at me with his mouth wide open and not saying anything. I told him, ‘You have to leave buddy. You are trespassing on my bus.’” That’s when Fox “leaned in and started punching my crotch and breast.”Bormann says, “I took one hand to his jaw and he was spitting blood. He stumbled backwards.” “This was my self-defense,” Borman says adding, “This was the only way I could protect myself…..from a man beating up on a woman.”Bormann says she’s meeting with prosecutors todayand may press charges.
