Images of seven men police would like to identify have been released following alleged racist incidents during West Ham United's Europa League match against Eintracht Frankfurt.
Several home fans were seen making racially motivated gestures towards visiting supporters, including some making Nazi salutes, police say.
The match at the London Stadium, which West Ham lost 2-1, was on 28 April.
Det Con Phil Dickinson said "abhorrent gestures and comments" were made.
Do you recognise these men?
