From Wiki;
Horst Kopkow (November 29, 1910 in Ortelsburg, East Prussia, Germany - October 1996 in Gelsenkirchen, Germany) was a Nazi Germany SS major who worked for German Security police and, after the war, was concealed by British intelligence so that they could use his knowledge in the Cold War.
Kopkow also investigated the July 20 plot, an attempted assassination against Hitler.
At the end of the war, British military police arrested Kopkow in a Baltic village on May 29, 1945. By that time he would have been implicated in 300 deaths of Allied agents.
