The Polish authorities are still investigating an anti-Semitic march by a far-right Polish group in the former Auschwitz concentration camp in southern Poland that coincided with last month’s World Holocaust Day.

“If it is proven that a hate crime was committed or that the law was otherwise violated, all state agencies, including the prosecutor’s office, will act accordingly,” said Michal Dworczyk, head of the Prime Minister’s Chancellery.

Around 50 people took part in this march organized by the far-right Polish Independence Movement Piotr Rybak, the leader of the march, who was imprisoned in the past for burning a puppet symbolizing a Jew in a protest.

The extremists placed a wreath of flowers under the slogan “In memory of the Polish Holocaust”, and sang Poland’s national anthem before being forcefully disbanded, but not before blaming Israel and the Jewish people for “doing everything possible to manipulate Polish history”.
