Alexei was detained on February 23, 2021, and held in pretrial detention pending trial. In August 2021, he was convicted of "active participation in group actions that grossly violated public order" for his participation in the post-election protest that took place on September 13, 2020, in Minsk, as well as for attempted theft.
In addition, the Minsktrans company filed a civil claim for damages in the amount of almost 29 thousand rubles.
At the time of his arrest, Alexei had an outstanding criminal record and was serving a restricted-liability sentence without being sent to a correctional facility; he had two months and three days remaining on his sentence.
In November 2023, he was released, having fully served his sentence imposed by the court.
