Resident of the Irkutsk region, mathematician. On 20 June 2023, he was detained after a search as part of a case of public justification of terrorism because of two publications, one of them devoted to a strike on a strategic bomber airfield in Engels in December 2022. Shibaev was released on his own recognisance. However, he was later taken into custody. Presumably, after the case went to trial, Shibaev was released from custody. On 19 January 2024, he was sentenced to four years in a general regime colony.
