The club were reported to the Football Association following an incident after the home game against Northampton Town on December 8 when one of the match officials was struck by an empty plastic bottle.
After an appeal by the club the spectator concerned came forward to admit responsibility.
Following discussions that also involved Sussex Police and the club’s safety and security team, the supporter has been banned from attending our next three home fixtures. The supporter has also agreed to make a donation to the EFL’s charity partner Mind.
The supporter has asked that the following statement be issued on his behalf:
"I would like to put on record how sorry I am for the incident that occurred after the game against Northampton.
I would firstly like to apologise to the official the bottle struck and I hope it has not had any damaging effect on him and hope it doesn’t in the future.
I would also like to apologise to the club and to all individuals as this has caused extra work.
I understand how proud the club are of their good reputation and the reputation it has of welcoming families to the stadium. I hope my actions haven’t tarnished its good reputation.
Lastly, I would like to apologise to all fans who were upset/angry by my actions. I can only explain that this happened due to being frustrated and upset but that this does in no way justifies how I behaved and again would I like to put on record that I am sorry.
I am a passionate supporter but this came out in the wrong way. I love my club but this is no way to show it."
The Football Association have since informed the club that it will not be taking any disciplinary action on this matter, but has warned that it may do so if there are reports of spectator misconduct in future.
Operations Director Kelly Derham said: "It goes without saying that the club does not condone any actions which brings our good name into disrepute. Football ignited passions but, regardless of how we view what happens on the field, I would appeal to all our supporters to uphold the good name of the club on matchdays by behaving responsibly."
