Joyce Maxine Gregory, 35, was charged with malicious castration.
City police allege Gregory was arguing with an unidentified older man Saturday morning and when he went outside to call authorities she followed him and grabbed his scrotum.
He ran to a nearby rescue squad building for assistance, the TV station said, and police officers arrived to take Gregory into custody. She allegedly pulled down her pants and urinated in the backseat of the patrol car.
It wasn't reported what the argument was about.
