I wasn't there either, but let's not take insult at what Lancsdave said:
"I'm not defending anything the steward may or may not have said, but lets get both sides"
I think we're all aware of how a hot-head steward or a humourless copper can ruin things for fans or a club, but what Lancsdave wrote is, or ought to be, simply the basis for what passes for justice in this country.
If it happened as described then the lad in question and witnesses should at least contact the club and make an official complaint about the steward's behaviour, so both sides can be taken into account.
