The FSB officers arrested a resident of the Leningrad region, who is suspected of preparing sabotage at a train transport facility on the orders of the Ukrainian special services. In 2024, the man was recruited by a member of a terrorist organization banned in Russia. In addition to preparing attack, he collected and passed on information about the location of Russian military facilities and gas stations in the northern capital. A 5 kg ready-to-use improvised explosive device and a smartphone containing correspondence with members of a terrorist organization in Ukraine were confiscated from the suspect.
