The Football Association is seeking observations from Luton over chants heard at their match against Liverpool on Sunday which indirectly referenced the Hillsborough disaster.
The taunts were sung by some home fans during the second half of the 1-1 Premier League draw at Kenilworth Road, and the FA says it is now looking for information from Luton as well as further detail from the police.
“We strongly condemn chanting of this nature and will continue to work closely with our stakeholders across the game, including the clubs, leagues, fan groups and the relevant authorities to proactively address this issue,” an FA statement said.
Ninety-seven football fans died as a result of a crush at an FA Cup semi-final match between Liverpool and Nottingham Forest at Hillsborough in Sheffield on April 15, 1989.
