In July 1941, during the Continuation War, Ojasti, who worked as a superior in ValPo's Rovaniemi department, was ordered to join a 12-man Finnish group assisting German SS-Untersturmführer Wilhelm Laqua, the commander of Einsatzkommando Finnland, in Kirkenes, Norway.

In the fall of 1941, men from the Finnish group worked in Nazi concentration camps in Norway.

Some of them also moved with the Germans to the Soviet side in Karelia, where they supervised the local population and hunted for communists.

At the end of the Continuation War and Finland switched sides, Ojasti joined the pro-German movement, and was transferred to the service of the German security police under Laqua.
