A Calgary police officer was injured while sitting in his car when a man came out of nowhere and broke his window with a club.
The bizarre attack occurred at 17 Avenue and 4 Street S.W.
Two officers in a patrol car were dealing with an unrelated incident when a man walked up to the car and smashed a window with a club.
One officer inside the vehicle was taken to hospital after being showered with glass, getting pieces lodged in his face and eye.
Inspector Keith Cain says it took a lot of force to break the two passenger side windows.
"The bars on the back windows were bent and the club that he had broke in two on the second swing, So he was swinging with quite a bit of force,"
The partner of the injured officer deployed a Taser during the footchase, but he got away.
Other officers swarmed the area looking for the suspect but have since turned up nothing.
