The Federal Prosecutor’s Office announced the arrest of Sergej K., who is believed to have maintained ongoing contact with a Russian intelligence agency since May 2025. He allegedly transmitted sensitive information regarding Germany’s military support for Ukraine, details about the German defense industry, and photographs of military convoys, including those of NATO states. This arrest reflects a broader trend observed by security agencies since the onset of the Russian invasion of Ukraine, highlighting Moscow’s interest in undermining the logistical and technological frameworks of Western support for Ukraine.
