Leyton Orient have vowed to act after homophobic chanting was heard from sections of Luton fans during their League Two match on Saturday.
Fans reportedly chanted "Do you take it up the a***?" to a group of men in a block of flats which overlooked the Matchroom Stadium.
Orient released a statement following the incident, which read: "We were made aware of homophobic chanting from sections of the Luton Town fans and will be dealing with it retrospectively. All information will be passed on to Luton Town.
"We do not condone racial or homophobic chanting at Leyton Orient FC and any such offender would be dealt with accordingly."
Luton said they had been unaware of such chants, but said the club would look at what had happened.
A Luton spokesman said: "We will take a review of the situation on Monday, but as a club we do not condone any kind of discriminatory chanting or comments from our supporters, and any serious abuse will be dealt with."
The match itself saw Orient suffer their seventh defeat of the campaign, as goals from Cameron McGeehan and Danny Hylton earned Luton a 2-1 win.
Orient are now one place above the relegation zone in League Two, level on points with Barnet.
