Calgary police officers’ actions were justified when they shot a knife-wielding man earlier this year, a provincial investigation has concluded.

Alberta Serious Incident Response Team executive director Clifton Purvis said the investigation determined the man was suffering from a mental illness and investigators believe he was suicidal.

“We concluded that his intention in approaching the members of the Calgary police service was that they shoot him,” Purvis said, adding the man was co-operative throughout the five-month investigation.

ASIRT investigators are confident the police actions were lawful when they shot the man as he approached them with a knife in a downtown apartment on May 26, 2009, Purvis said.

The man was shot with a rifle once when he refused to drop the knife.

The man recovered from non-life-threatening injuries.
