A Polish court issued a European arrest warrant on Tuesday for a former neo-Nazi leader suspected in the theft of the infamous “Arbeit Macht Frei” sign at Auschwitz. Rafal Lisak, spokesman for Krakow’s district court, said that Anders Hogstrom, 34, of Sweden, was suspected of incitement to commit theft of a cultural treasure. The sign, whose words are German for “Work Sets You Free,” was stolen in December from Auschwitz in southern Poland. The sign was found three days later, and five Polish men were charged with its theft.
