Police say a 15-year-old girl was airlifted to hospital with life-threatening injuries after a single-vehicle accident in Cape Breton.

Sergeant Sheldon O’Donnell says Cape Breton Regional Police received a call of a single-vehicle rollover at 11:55 p.m., about 20 kilometers outside Sydney.

The car appeared to leave the shoulder of the road, then veered left, crossing the centre line and landing in the ditch. Fire crews from Bateston, Mire Road, and EHS found a 15-year-old girl badly injured.

“EHS were attending to four occupants who were out of the vehicle on their own and there was one female teen trapped in the vehicle,” says O’Donnell.

The teen was immediately airlifted to a Halifax hospital in serious condition.

The sedan had five occupants, ranging from 14 to 24 years old. Police say the vehicle was driven by a 21-year-old man.

“As a result of the extraction of the last victim of the car, four of them were transported to the Cape Breton Regional Hospital,” says O’Donnell.

Police say the Traffic Safety Unit has seized the vehicle for inspection.

They do not believe drugs or alcohol were a factor.
