The Leeds United Supporters Trust (LUST) claim Millwall fans sang songs mocking the killing of two Leeds fans in Istanbul, Turkey. However, some fans at the game also claim to have heard abuse regarding the 1958 Munich air disaster coming from Leeds supporters.
"Before kick-off, a section of the home crowd began chanting about the deaths of two Leeds United fans in Istanbul, Turkey," a LUST spokesperson told the IBTimes UK.
"This was in full view of many stewards of Millwall Football Club and the Metropolitan Police. These chants are totally unacceptable and, in our opinion, caused alarm and distress to the Leeds fans within the ground.
"As a result of the inaction from stewards of Millwall Football Club and officers from the Metropolitan Police, further chanting of a similar nature continued with other sections of the home support joining in, especially throughout the latter stages of the game where they were widespread throughout the ground."
