RCMP have seized an SUV that is believed to have struck an RCMP officer, and a man who had just been arrested, in a hit and run early Sunday morning.

A disturbance complaint initially called White Butte RCMP to an event centre just west of Regina, when they became aware of threats made at a gathering that related the use of firearms, authorities said in a statement.

A 56-year-old Regina man was arrested after the RCMP officers responded to the disturbance call.

Authorities say the three RCMP officers were standing on Sherwood Forest Road with the man in custody when an SUV drove towards them.

One RCMP officer was in the ditch off the roadway while the second officer grabbed the arrested man and tried to get out of the way. The third officer and the arrested man were struck by the SUV, which also sideswiped an unmarked police vehicle.

Shots were fired at the vehicle in an attempt to stop it, and though the vehicle slowed down, it managed to drive away from the scene.

The 42-year-old constable who was struck by the vehicle is in hospital with serious injuries. The arrested male sustained non-life-threatening injuries. A second White Butte RCMP constable also suffered minor injuries as a result of the incident. He has received medical treatment and been released.

RCMP later seized an SUV believed to have been involved in the hit and run. Forensic investigators are examining the vehicle to try to identify a suspect.
