Brighton have banned indefinitely a man convicted of shouting homophobic abuse at home fans during the Premier League game against Arsenal at the Amex Stadium on 2 October.
Luke Reece, 21, was overheard by club staff and tried to leave the ground after realising he had been spotted, but was apprehended by police.
He was convicted of indecent chanting at a football match after a trial at Brighton Magistrates Court on Tuesday and given a three-year football banning order.
Reece was also fined and ordered to pay costs.
In announcing an indefinite ban from the Amex, Brighton said: "We have a zero-tolerance approach on all forms of anti-social behaviour and this includes any form of abuse.
