Towns with over 10,000 residents having a municipal police department were also obliged to have a municipal criminal investigation division—Gemeindekriminalpolizeiabteilung. It was supervised by the nearest State criminal investigation department (Kripo-Stelle). As of 1943 all municipal criminal investigation divisions with more than 10 detectives (i.e. mainly in cities with more than 50,000 residents) were transferred to the state Kriminalpolizei.[3]
