Tottenham and Arsenal are united in their determination to identify fans from both clubs who were guilty of offensive chanting during Sunday's north London derby at White Hart Lane.
Spurs' 2-1 victory over their bitter local rivals was overshadowed by abusive jeers from both sets of supporters. Sections of the home crowd taunted Arsenal manager Arsene Wenger, while some away supporters were widely condemned for mocking the deadly gun attack on the Togo team bus in January 2010 which Emmanuel Adebayor survived.
Arsenal intend to work closely with their counterparts at White Hart Lane to root out the offenders. A joint statement read: "Both clubs were extremely disappointed to hear the chants from supporters at [Sunday's] game. Neither club tolerates foul language, racist chanting, homophobic chanting or any anti-social behaviour from its supporters."
It continued: "We shall be working closely with each other to identify the individuals involved."
Tottenham manager Harry Redknapp launched a stinging attack on the Arsenal fans on Sunday night, describing the chants at former Gunners striker Adebayor as "disgusting".
Tottenham have since confirmed that several fans from both the home and away sections of the crowd were ejected from White Hart Lane during the game. In line with the club's zero-tolerance policy on abusive chanting, they have also promised to ban any guilty party for life.
Under a subheading of 'Spurs against discrimination' on their official website, Tottenham called for help from their fans to find the perpetrators.
"We should like to remind all of our supporters that we do not tolerate discrimination of any sort at the club, on the pitch or in the stands," the statement read.
"If you experience any form of discrimination, help us to eliminate it from football.
"We have a fantastic atmosphere at the Lane and by working together we can prevent the small minority ruining it for everyone."
