Weapon waved by man shot by RCMP in southern Alberta was BB gun: investigators

REDCLIFF, Alta. - Investigators have seized a gun they believe was pointed at an officer who shot and wounded a man at an RCMP detachment in southern Alberta.

The Alberta Serious Incident Response Team says the weapon was a black Smith and Wesson 122-calibre BB gun.

ASIRT says a man walked into the detachment in Redcliff on Monday and pointed what appeared to be a firearm.

He was taken to hospital after he was shot and remains there in critical but stable condition.

The RCMP have charged 33-year-old Bernard Norman of Redcliff with possession of a weapon dangerous to the public and assault on a peace officer.

A court appearance has yet to be determined.
