Yes, I've seen plenty of footage on Utube.
This is the sort of behaviour that is often associated with football, not something we need in RL.
Glad that it was brought under control fairly quickly with the help of the police, it really doesn't take much more than this to escalate and get completely out of control.
I hope the RFL and police find the culprits and make an example of them, violent incidents are few and far between in RL but the consequences of these actions needs to be severe enough to deter the few mindless people out there who could potentially cause these incidents to occur in the future
