A 26-year old man is said to be in stable condition after an attack at Mount Royal park.
Police say he was attacked by three men, punched and kicked, after he told them to stop tearing breanches from a tree.
"The victim was found lying on the ground by police officers. He was transported to the hospital in serious condition with serious injuries to the upper body", said police spokesman Francois Collard.
The suspects were still at large.
