Airdrie have punished individuals with lifetime bans following a League One match with Cove Rangers.
The Diamonds have also barred another for online homophobic abuse.
It comes after Airdrie had announced they were working with Police Scotland after Cove fans were 'attacked' in the aftermath of a 1-1 draw between the pair last month.
They warned recently that the 'maximum action will be taken to help eliminate all forms of unacceptable behaviour at football.'
Now three have been identified and another has also faced punishment after online comments.
An Airdrie statement reads: "The club have issued lifetime bans to three individuals who attended the home game against Cove Rangers.
"The club have also issued a ban to a further individual for online homophobic abuse.
"Airdrieonians Football Club will not tolerate any forms of abuse, discrimination or unacceptable behaviour."
