[Closed] I was out along the canal yesterday with my mates...

...we were standing there minding our own business and trying to get rid of an older guy that we don't like because he causes too much trouble. He was blocking the path, but there was plenty of room to get round us. The next thing we know this guy starts shouting at us to let him through. He then tries to force his way through - nobody did anything to provoke this. He gets through OK, but then the guy we were trying to get rid of chased him and pulled him off his bike. We went over to try and split up the fight that was going to happen, and see that he was OK, but the older guy chinned one of my mates. What should we do? Any way of tracing the older guy because he's fractured my mates ribs and he has asthma?

Two sides to every story. Truth is probably somewhere in the middle - it always is.
