A right-wing extremist member of a group that still believes in Adolf Hitler's World War Two-era German "Reich" was convicted of murdering a police officer last year and sentenced to life in prison on Monday, German media reported.
The man, known only as Wolfgang P. because of German court rules, fired on policemen attempting to search his flat for illegal weapons in October last year, killing one of them.
The Reichsbuerger (Reich Citizens) movement, which authorities believe may have up to 900 far-right members, regards the modern German state as illegitimate.
Its members say they owe allegiance only to the German Reich, or state, despite its abolition in 1945. Germany's domestic intelligence agency placed the movement under observation after the killing as a possible unconstitutional extremist group.
