The Independent Investigation Unit (IIU) is investigating the arrest of a 60-year-old man in Onanole early Wednesday morning.

The RCMP report the man had threatened to shoot a woman, and later locked himself inside of a residence, refusing to comply with police orders.

When the man eventually surrendered to police, he was taken to hospital with a self-inflicted gunshot injury.

The IIU is mandated to investigate because the injuries sustained during the arrest required admission to hospital, and involved an injury caused by the discharge of a firearm.

Witnesses with video footage or any other information to assist the investigation, are asked to contact the IIU toll-free at 1-844-667-6060.
