Poland has asked Sweden to question three suspects about the theft of the “Arbeit macht frei” sign at the Nazi death camp at Auschwitz, Polish prosecutors said on Thursday. “We are asking Swedish justice authorities to question three people, all ofthem Swedish citizens, in the presence of our prosecutors investigating thecase,” Krakow regional prosecutor spokeswoman Boguslawa Marcinkowska told AFP. “The questioning is very important to the investigation,” she added, but she refused to reveal the identity of the persons to be questioned. Polish media reports say that Swedish millionaire Lars-Göran Wahlström allegedly asked Anders Högström to arrange the theft late last year of the infamous sign.
