The conduct of a group of Edmonton police officers is being questioned after a video posted online appears to show an officer repeatedly kicking a suspect before slamming him head first into a wall.

The Edmonton Police Service professional standards branch is investigating the arrest, which was captured from above by a citizen in a nearby apartment on June 11.

A two-minute, 20-second video posted to Twitter shows six uniformed officers take down a suspect in the parking lot of an apartment building near 106th Street and 99th Avenue.

The 26-year-old man was allegedly driving a stolen Chevrolet Colorado pickup truck, EPS spokesperson Cheryl Sheppard said in a news release Tuesday afternoon.
