Police say a man suspected of assault has died while under investigation.

The Onion Lake RCMP says it was looking into the assault report on December 1st and found the suspect in a vehicle still in the Onion Lake Cree Nation.

The 43-year-old man was reportedly holding a gun while sitting inside. As officers spoke to him, they say he shot himself and was declared dead at the scene.

The RCMP claims none of its members’ guns were fired. The Province of Saskatchewan has appointed an Investigational Observer to work with mounties on their investigation.
