A surveillance camera captured the encounter between the two men. In the video, Harris can be seen striking the suspect with his car, then getting out of the car, at which point a physical and verbal altercation occurs. Harris told WISN that the man made it appear as if he had a weapon in his pocket, so he went back to his car and grabbed a hammer to defend himself.
Police arrived quickly on the scene and arrested both men. The suspect was arrested on a robbery charge and Harris was arrested on an outstanding misdemeanor domestic battery charge, WISN reported. Wauwatosa Police Department officials said charges against Harris for his actions in taking down the robbery suspect are not being pursued.
