Resident of Moscow. Detained on October 3, 2023 after a search. Accused of spreading deliberately false information about the Russian Armed Forces. Seleznev was taken into custody. Before the court hearing on October 4, 2023, Seleznyov, who was in a convoy car, felt unwell and lost consciousness. An ambulance was called for him, and the doctors recorded the man's high blood pressure (150/90 with the age norm being 90/60). Nevertheless, the hearing took place. In November 2023, the lawyer reported that Seleznev was subjected to pressure in the pre-trial detention centre: he had not been taken for a walk for a week already, and was kept in a smoky cell with four previously convicted persons, one of whom insulted him. At the same time, according to the law, persons charged with criminal offenses for the first time must be kept separately from those who have already served their sentences in places of detention. Later Seleznev was transferred to a regular cell. In December 2024, it was reported that Seleznev was in a cell with 22 beds, where about 30 detainees are kept. They have to take turns sleeping. On January 27, 2025, Seleznev was sentenced to eight years in a general regime colony.
