Sonderabteilung Lola

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.

Under cover the group contacted people who were anti-Nazi, through whom they infiltrated the Norwegian resistance movement. 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. These kinds of infiltration operations were called "provocation business", to expedite action and subsequently arrest the suspects. Rinnan even called this a "game in the negative sector". The group worked towards the entirety of Central Norway, i.e. Trøndelag, Møre and Romsdal, even Nordland. Rinnan wanted to expand operations to Oslo, but this was possibly stopped by the Germans.
