The initiative for the force came from the later chief Karl Marthinsen and other prominent members of the collaborationist party Nasjonal Samling.
At its peak, in 1944 there were 350 employees in Statspolitiet, in addition to a larger number who collaborated or rendered services for them.
[5][6] The general of Statspolitiet, Karl A Marthinsen was assassinated by the Norwegian resistance movement on 8 February 1945.
This caused massive reprisals, in which 34 imprisoned resistance fighters were executed at Akershus Fortress.
The death sentences for the Statspolitiet officers Reidar Haaland, Arne Saatvedt, Hans Jacob Skaar Pedersen, Holger Tou, Ole Wehus, Olav Aspheim and Einar Dønnum were fulfilled, the officers being executed by firing squad.
