Sonderabteilung Lola (in Norway also known as Rinnanbanden (Rinnan gang)) was an independent group under the German Sicherheitsdienst in Trondheim, KDS Drontheim Referat IV, and consisted of around known 50-60 Norwegians informants who worked for Henry Rinnan, many of whom were former frontline soldiers in the Waffen SS. This group was not known to the vast majority of Norwegians, including the members of the Nasjonal Samling party, until after the war. Rinnan himself used a variety of aliases.
