Polish authorities detained two Canadians who allegedly stole spikes from a railway line that shipped Jews to the Nazi German death camp of Auschwitz-Birkenau, museum staff told AFP on Monday. “Security guards detained two Canadians in their twenties shortly before noon on Saturday in possession of two spikes that held down the rails,” said Bartosz Bartyzel, a spokesman for the museum at the World War II camp. “The two men were handed over to the police,” Bartyzel said.”For us, this is a case of desecration of a place of memorial. These items are priceless,” he said.
