The Lithuanian Security Police (LSP), also known as Saugumas (Lithuanian: Saugumo policija), was a local police force that operated in German-occupied Lithuania from 1941 to 1944, in collaboration with the occupational authorities.[1] Collaborating with the Nazi Sipo (security police) and SD (intelligence agency of the SS),[2] the unit was directly subordinate to the German Kripo (criminal police).[3] The LSP took part in perpetrating the Holocaust in Lithuania, persecuting Polish resistance and communist underground.
