Sonderabteilung Lola (in Norway also known as Rinnanbanden (Rinnan gang) was an independent group under the German Sicherheitsdienst in Trondheim, KDS Drontheim Referat IV.

The Sonderabteilung ("Special Unit") consisted of around known 50-60 Norwegian informants who worked for Henry Rinnan, many of whom were former frontline soldiers in the Waffen-SS.

After a period of active work in the resistance group, both to gather information and build trust, the network was rolled up and the participants arrested and interrogated.

Before this, he had reported resistance people to contact the German officers Gerhard Flesch and Walter Gemmecke, so that they were arrested, tortured and possibly killed, or put in concentration camps.

Rinnan drove the group completely by their own rules and on a couple of occasions killed Norwegians without German prior consent.
