The Moscow Times reports that the suspect, identified as Sergej K., has been in continuous contact with a Russian intelligence handler since at least May last year and is accused of sharing information on German defense contractors developing drone and robotics technology, as well as sending photos of German public buildings. Al Jazeera confirms the continuous contact and expands on the types of information passed, including details about German military aid for Ukraine and photos of NATO convoys. AP News notes the arrest and the ongoing involvement of defense contractors and potential sabotage targets, while noting Western officials’ warnings of a broader surge in Moscow-linked plots since 2022.
