Yegor was arrested in February 2021 and later convicted of setting fire to a T-72 tank aboard a military train at the Stepyanka railway station. According to the case file, on the night of January 31, 2021, he threw a Molotov cocktail with the inscription "OGSB" at the tank. His actions were classified as an "act of terrorism." According to the prosecution, Yegor committed the arson based on his political views.
In early October 2023, it was announced that Yegor had been transferred to Pretrial Detention Center No. 1 in connection with a new criminal case opened under the article "organizing and preparing actions that grossly violate public order, or active participation therein." In this case, he was sentenced to an additional six months in prison.
