(CNN) -- Czech authorities announced Saturday that they have arrested a 29-year-old man who expressed admiration for Anders Behring Breivik, the self-declared ultranationalist who has admitted killing 77 people in Norway last summer. Video broadcast on Saturday by CT24, a public broadcast station in the Czech Republic, showed the handcuffed suspect flanked by police. Dressed in a short-sleeved shirt, the unidentified man appears to be smiling during much of the videotaped walk. Tomas Tuhy, a regional director of the Czech Republic Police, said authorities confiscated "police or prisoner" uniforms during their search of the suspect's apartment, as well as some police equipment. Pictures published on CT24's website showed explosive detonators, firearms, ammunition, and what appears to be a police uniform, that were seized as part of the investigation.
