A worker at Radio Shack was arrested for punching a customer.
Officers arrested 52-year-old James Knol of Eau Claire, Wisconsin for disorderly conduct and battery.
According to the police report, 56-year-old Leigh Carey was trying to return something at an Eau Claire Radio Shack location.
Carey told investigators Knol wouldn't let him, so he asked to talk to a manager.
That's when he says Knol started punching him and a witness called 911.
Knol is due in court May 19.
