The public prosecution department is investigating chants by supporters at Wednesday night’s celebrations marking FC Groningen’s KNVB Cup win.

RTL news reports that the department is looking at the text ‘En wie niet springt die is een Jood’ (who does not jump is a Jew) which was changed before an on-stage chat with Johan Kappelhof, who formerly played for Ajax.

Ajax supporters call themselves Jews as a nickname, despite pleas by club officials to drop the tag. Opinion as to why they use the Jewish monicker is divided.

According to RTL, the department considers the texts chanted on Wednesday as ‘extremely undesirable’ and will study broadcasts of the event on Thursday.

Some 30,000 people turned out to celebrate the club’s victory. It was the first time since the club was founded in its present format that they have won the KNVB Cup.

Utrecht

Last month, the public prosecution department launched an investigation into anti-Jewish chanting at a league match between FC Utrecht and Amsterdam club Ajax.

Supporters were clearly heard chanting about having a mother in the SS and ‘Jews burning best’. The video was placed online and picked up by the Telegraaf newspaper.
