Last night, an eyewitness said: "The guy ran up the road and another man followed him - I thought they were messing about at first.
"Then these two other guys came up and all three started attacking him. The guy being followed was on the floor - he was getting his head stamped on and another guy looked like he was punching him towards the face and neck.
"I don't know if they were hitting him or stabbing him - there was blood all up the road. I've been told he's been stabbed but I didn't see a knife."
