"We have already issued the arrest warrant for the Swedish suspect to be brought to police headquarters in Krakow," Boguslawa Marcinkowska of the Prosecutor's Office in Krakow said Friday.
Five Poles arrested Dec. 21 -- three days after they allegedly stole the infamous "Arbeit Macht Frei" sign from the World War II German Nazi death camp -- said they were paid to steal the sign by a former neo-Nazi in Sweden, Poland Radio reported.
He intended to sell it "for millions" to a collector, allegedly living in Great Britain, Poland Radio said.
Swedish press reports identified the suspect named in the warrant as alleged former neo-Nazi Anders Hogstrom.
"My role was to go get the sign in Poland," he told a Swedish daily newspaper Expressen. "I was the middleman and was supposed to take care of the sale."
Hogstrom, described as a former leader of a 160-member strong neo-Nazi group based in southeast Sweden, told the newspaper the money from the theft would be used to launch a campaign against parliament and Swedish politicians.
The sign was found in northern Poland, cut into three pieces.
