The gang that ordered the theft of the infamous 'Arbeit Macht Frei' sign from the Auschwitz death camp memorial were planning to sell it to fund attacks against the Swedish prime minister and parliament, the Times reported on Thursday. "We are aware of the information about the alleged attack plans," Patrik Peter, a spokesman the Swedish security police was quoted as saying by the British newspaper. "We have taken actions. We view this seriously." Polish police found the sign on Sunday and said they had detained five young men. The purported former leader of a Swedish Nazi group told the Swedish Aftonbladet newspaper that, "We had a person who was ready to pay millions for the sign." The unnamed source told Aftonbladet that the money would pay for an attack on the home of Swedish Prime Minister Fredrik Reinfeldt and on the Swedish Foreign Ministry. A third attack allegedly involved plans to bombard Swedish MPs from the public seats of the parliament. "The sign was to be delivered to Sweden, since it was here the deal should be made," the source said, according to a Times translation. "My role was to find a buyer. We had a person who was willing to pay millions but he had no political agenda. These things have a huge collector value... The biggest collectors are from England, the United States and France."
