In that case you are wrong in saying the steward was relieved of his duties I think. The bloke concerned only packed it in this season. I also agree with a previous poster that you remove the aggressor first and deal with the rest after (I've run pubs in Poole and that's how we used to do it). However I would agree with you, having been there that night and heard the poor lad screaming, that crowding round and taking photos was very out of order.
