A Swedish neo-Nazi has pleaded guilty to involvement in the theft of the infamous "Arbeit Macht Frei" sign from the gates of Auschwitz. As part of a plea bargain, the thief will serve close to 3 years in a Swedish prison. Five Poles, who authorities say were involved for profit instead of political reasons, have also been jailed for the theft, AP reports. Prosecutors say they believe the theft was masterminded by another Swede with neo-Nazi links, who is now being investigated by police. (More Auschwitz stories.)
