Polish police have determined that the robbery of Auschwitz-Birkenau's Nazi death camp's 'Arbeit Macht Frei [Works Sets You Free]' sign was not committed by neo-Nazis. So, it was probably a theft-to-order for right-wing private antiquities dealers.
Krakow District Police Chief Andrzej Rokita stated that 'none of the five are members of a neo-Nazi group.... Their intent was undoubtedly robbery-related'.
Perversely (in both senses of the word), Holocaust deniers have stolen 'soil and other artefacts' as "evidence" that Nazi extermination plans had been 'exaggerated'.
These thieves could have been neo-Nazis unconnected with a neo-Nazi group; but the Polish police have presumably searched the thieves' homes and found no neo-Nazi literature, no Nazi memorabilia, etc., so they were (very probably) not.
Nevertheless, the police know nothing about the contractors who ordered the theft; they could still be neo-Nazis; but it is becoming more likely that they are right-wing private antiquities collectors.
I can understand the Daily Telegraph classifying this story as 'Middle East / Israel' news; but I think it should be 'Europe / Poland' news.
