Borussia Dortmund have called on witnesses to report any information about alleged anti-Semitic chanting during Saturday’s Bundesliga derby against Schalke to the police.
“Anti-Semitism is not an opinion,” the club wrote on Twitter on Tuesday.
The Research and Information Center on Anti-Semitism in North Rhine-Westphalia (RIAS NRW) was the first to report the allegations related to the 2-2 draw between the two biggest clubs in the German state.
“On Saturday, some Dortmund fans sang anti-Semitic chants in the guest block of the Revier derby in Gelsenkirchen. They wore similar sweaters with the symbol of a hooligan and the words ‘Fight together’ printed on them in old German script.” center wrote on Facebook.
“Even before kick-off, individuals from the group addressed the opposing team and fans with shouts of ‘you Jews’ in a clearly derogatory manner.”
Dortmund have long been known in Germany for their strong stance against anti-Semitism. Managing director Hans-Joachim Watzke received the prestigious German Josef Neuberger medal last year for his club’s fight to protect Jews.
