Feuding street gangs may be responsible for an early Sunday shooting in a suburban Montreal strip club that left four people injured, police said.

"There are certain elements found at the scene that is making us believe this may be a street gang conflict between two rival groups," Laval police Constable Frank Di Genova said.

"It's not confirmed 100 percent, but it seems to lean that way."

All four victims -- three men who suffered gunshot wounds and a woman hit by flying glass -- were expected to recover, said police, who had made three arrests. No names had been released.

The Canadian Broadcasting Corp. reported there were about 150 people inside and outside the bar when the shooting broke out about 2 a..m.
