Greater Manchester Police arrested one person after alleged tragedy chanting during the FA Cup quarter-final between Manchester United and Liverpool.
Offensive songs were allegedly heard during United’s 4-3 extra-time win over their rivals at Old Trafford on Sunday.
“We are all familiar with fans taunting their opponents … but this is generally done in good humour and without offence,” said police.
“The incidents today crossed the line of what is acceptable.”
“Incidents of tragedy chanting will not be tolerated and will be dealt with robustly,” read a statement, adding: “We will work closely with both clubs to identify anyone responsible for committing offences during the event.”
Earlier, the FA “strongly” condemned “any offensive, abusive and discriminatory chants in football stadiums” and said it would liaise with Greater Manchester Police.
“We are determined to stamp this behaviour out,” it added. “It is entirely unacceptable and can have a lasting and damaging impact on people and communities within our game. It must stop, and we support any club and their fans who try to eradicate this from the terraces.”
