Police in Vancouver are investigating one of their own after a video was posted to Facebook that appears to show a plainclothes officer punching a cyclist in the head during an arrest Tuesday night. Vancouver police spokesperson Sgt. Randy Fincham says the cyclist was "allegedly confrontational with police" after being stopped at Robson and Beatty streets for apparently running a red light. Cyclist Andishae Akhavan insists he was not resisting arrest, and says there was no reason for the officer to punch him in the face.
