Brighton have asked police to investigate whether there were monkey chants aimed at players during their game at Burnley last Saturday, reports BBC Sport.
Clarets fans booed Brighton defender Gaetan Bong during the 0-0 draw.
Bong accused West Brom's Burnley-born striker Jay Rodriguez of racially abusing him in a match in January, a charge subsequently found "not proven".
The Seagulls have asked Sussex police to speak to their Lancashire counterparts over claims there were monkey chants during the match.
Burnley said they are aware of the police involvement in the issue.
