Loon Lake RCMP say a 15-year-old boy has died as the result of a single-vehicle rollover Monday afternoon.

Police say the teen was the driver of a vehicle travelling at high speeds on Treatment Centre Road when he lost control of the vehicle and rolled multiple times on the gravel road.

The driver and front passenger were ejected from the vehicle.

Life-saving efforts were unsuccessful and the teen died at the scene.

The front passenger, a 15-year-old girl, was transported to Saskatoon hospital by air ambulance with serious but non-life-threatening injuries.

The two rear passengers, a 14-year-male and 14-year-old female, were taken to Meadow Lake hospital for treatment of minor injuries.

Alcohol is not believed to be a factor.
