RCMP believe that the cause of a serious collision on Highway 4 from Thursday may have been a firearm discharge.

On May 15th at 9 a.m., Battlefords RCMP received a report of a rollover in the Mosquito Grizzly Bear’s Head Lean Man First Nation/Red Pheasant Cree Nation area.

The four occupants of the vehicle were taken to hospital, two with serious injuries and two with non-life threatening injuries.

Officers are also investigating a report of a firearm discharge on Highway #4 around the same time of the collision, and they are looking into any possible connection between the two incidents. Investigators are searching for a white pick-up truck in relation to this investigation.

If you see this truck, do not approach it. Report information to 310-RCMP or Saskatchewan Crime Stoppers. The investigation into the rollover continues, as well.
