This document reports on the legal proceedings against Mikhail Trepashkin, a former FSB colonel and lawyer who is a key figure in investigations into the 1999 apartment bombings. Following a traffic stop on the Dmitrovskoye Highway, Trepashkin was detained for illegal firearms possession, though he claims the weapon was planted. The narrative details a series of procedural irregularities, including his transfer between the Dmitrovsky and Volokolamsk remand prisons (SIZOs) and his re-arrest on November 5 despite a prior release order. Defense lawyer Elena Liptser argues the detention is politically motivated and plans to appeal to the European Court of Human Rights in Strasbourg. Additionally, the Chief Military Prosecutor's Office has accused Trepashkin of disclosing state secrets related to his former service in the FSB.
