Sergei, a retired lieutenant colonel who participated in a video message from reserve officers to the Belarusian military, was detained on July 16, 2021, following a search of his home.
According to Lukashenko's decree, he was stripped of his military rank after 28 years of impeccable service in the Armed Forces. Sergei is a father of four children, two of whom are minors.
In December 2021, he was charged with organizing, preparing, or actively participating in actions that grossly violate public order. Sergei was sentenced to restricted freedom without being sent to a correctional facility and released in the courtroom.
He was convicted again in October 2025. The appellate court sent the case back for retrial. Ultimately, during the retrial, the case was dismissed due to the statute of limitations, and Sergei was released from the courtroom.
