Polish police working with the FBI shut down a Polish neo-Nazi Web site and detained its suspected administrator, officials said Thursday. The suspect, identified only as Mariusz T., 31, was taken into custody early Thursday in the southern Polish city of Bielsko-Biala and is known to police for links to the neo-Nazi scene in southern Poland, Lower Silesia police spokesman Beata Tobiasz said. He is being questioned, Tobiasz said. The site carried "neo-Nazi contents" with "pictures and addresses or personal information of people of various ethnic backgrounds toward whom the organizers called for hatred and threats," Tobiasz said. The Polish language Web site served as a message board for a local chapter of the international neo-Nazi network known as Blood and Honor, police said. Polish police appealed to the FBI for help in shutting down the site, and the US owner of the Web site's server agreed to block it, Tobiasz said. Prosecutors were expected to press charges later Thursday.
