Facebook police punch video sparks Port Moody probe

Port Moody police say they are investigating an incident at the Golden Spike pub after a video was posted on Facebook that appears to show an officer punching a handcuffed man and throwing him to the ground.

The 18-second video clip of the incident was posted on Facebook, provoking allegations of excessive use of force.

Police say staff at the pub called 911 just after midnight Saturday, saying a man and a woman had been kicked out and the man was attempting to fight security staff.

"When officers arrived on scene they could hear the male and female yelling obscenities at the staff outside the pub. According to staff, both parties had been ejected from the pub for assaulting and threatening employees," said a statement released by the department.

"An officer placed the 30-year-old Coquitlam male under arrest for intoxication in a public place and causing a disturbance. Despite multiple warnings, the male was uncooperative during the arrest and was subsequently taken to the ground."

Police say both the man and woman were arrested, held overnight and released when they were sober.

The department says a review of the incident is underway and anyone with concerns over the conduct of the officers is encouraged to contact the department's professional standards section.
