Nottingham Forest are working with the police to identify fans who are believed to have directed homophobic abuse at Brighton players and supporters on Saturday.
The behaviour under investigation took place during a 3-2 victory for 10-man Brighton, who had Lewis Dunk sent off late in the second half at the City Ground.
Forest condemned the alleged conduct and assured there would be consequences for those involved.
A statement on the club's official account on X, formerly Twitter, read: 'Following Saturday's Premier League fixture against Brighton and Hove Albion, we have been made aware of some homophobic language aimed towards Brighton players and supporters from a minority of our fans.
'Homophobia, like all other forms of discrimination, has no place in football or society, and anyone engaging in discriminatory behaviour is committing a criminal offence. We are actively working with Nottinghamshire Police to identify the individuals involved, and they will be dealt with appropriately.
