German-Russian Dieter S. Sentenced to Six Years for Spying for Russia Including Sabotage Planning

On October 30, 2025, the Munich Higher Regional Court convicted Dieter S., a German-Russian national, to six years imprisonment for espionage on behalf of Russia, focused on sabotage of railway and military infrastructure in Germany. Two accomplices received suspended sentences. The court also confirmed his membership in the "Pyatnashka Brigade," a pro-Russian militia group designated terrorist by German authorities, active in eastern Ukraine since 2014. Confidential chat logs showed Dieter S. coordinated with GRU-linked units and militia command to recruit fighters and organize travel corridors for combat deployment. He denied allegations, claiming imagery was fabricated. The case underscores Russian espionage and sabotage efforts within Germany involving recruitment of local proxies and mapping critical infrastructure for potential attacks. The prosecution had sought over eight years, but the sentence was six years, evidencing a serious hybrid warfare threat.
