Hayes County sheriffs say a witness reported that two men dressed as clowns allegedly dragged a woman out of their Dodge minivan, assaulted her, and burned her face with a lit cigarette. They reportedly wrote “clown posse” on her face.

WSOC TV reported that the victim was treated by emergency responders at the scene. Deputies said that she appeared shaken up by the apparent attack.

Investigators believe this to be a random assault.
