The five teens, all students of the Grande Prairie Composite High School, were travelling in a car on the Correction Line just after midnight when it was reportedly struck by a GMC Sierra pick-up truck, RCMP said. 

The driver of the pick-up truck, a 21-year-old Grande Prairie man, sustained non-life threatening injuries. 

He allegedly fled the scene and was arrested a short time later by RCMP.  He remains in custody with charges pending.

An RCMP collision analyst is helping with the investigation. Speed and alcohol are being investigated as potential factors.

Officials are still on scene and motorists are being asked to find alternative routes as a portion of the Correction Line is closed.   

It is the second fatal crash involving teenagers in the province in a week. Four teenagers were killed late last Saturday in a single-vehicle rollover near the town of Magrath, in southwest Alberta.
