Sergei was arrested on March 23, 2021, for standing up for his mother when OMON and GUBOPiK were violently detaining her in her own apartment. He was convicted of "threatening to use violence against an internal affairs officer."
In 2024, on the day of his release, he was rearrested, and in July of that year he was re-convicted under the article “malicious disobedience to the demands of the administration of a correctional institution” - an article under which prisoners are tried for refusing to cooperate with the administration and for fictitious violations.
