Alberta’s police watchdog has cleared a Calgary officer of any wrongdoing in the fatal shooting of a man in the community of Redstone in 2018.

The victim, a 25-year-old man, was shot during a confrontation with police during which he attacked officers through the open window of a police cruiser with two knives, the Alberta Serious Incident Response Team (ASIRT) said.

The man’s shooting death happened on Aug. 31 after a series of interactions with police that took place over the course of about six hours.
