A 22-year old Union Township man was arrested Friday after banging his head through a patrol car window. Deputies responded to the scene after they received a tip that the man had warrants, and was at the location. When they arrived, they saw the suspect leaving from a bedroom window and arrested him. He broke free & was apprehended a short time later… that’s when he banged his head through the car window. He was treated & taken to the Isabella County Jail.
