Unpleasant player, unpleasant referee, unpleasant spectators, but you could argue however unpleasant, uncalled for and barbaric it was they all participated in their own demise, the player by headbutting and punching the Ref, the Ref by stabbing the player and now some spectators have been arrested and I expect it will go on possibly for years as feuds often do. Some people just like Chaos and violence and I'm not too sure what you can really do about them especially when they find like minded nutters to go head to head against:(
