Two people were seriously injured after their car flipped over several times before ending up in a ditch on the South Shore.
It was a couple of police officers on patrol who spotted the vehicle on the side of Industrial Blvd. in Châteauguay at about 3:35 A.M.
The driver, believed to be a man in his 20s was thrown from the vehicle during the crash. He remains in a critical condition.
The passenger, a woman in her 20s, was trapped inside; fire fighters needed the Jaws of Life to extract her. She was taken to hospital with serious injuries but is now out of danger.
So far no witnesses to the crash have come forward, and there were no calls made to 9-1-1 regarding the crash, making it hard for investigators to determine what really happened.
For now police can say alcohol was not a factor.
