Police are waiting to question a man who was attacked Wednesday night in downtown Montreal.

Around 11 p.m. several people started fighting near the intersection of Ste. Catherine St. and Cartier, next to the Papineau metro station.

One man was stabbed in the back with a knife, and rushed to hospital for treatment.

Police were not able to arrest anyone at the scene, and their searches overnight proved fruitless.

The victim is expected to survive.
