Anton Bialenski is a volunteer of Viktar Babaryka's campaign headquarters. He was detained in the framework of the "rioting case" (Article 293 of the Criminal Code).

Bialenski was held in the KGB pre-trial prison, then in pre-trial detention center No. 1 in Minsk.

On March 5, 2021, Judge Sviatlana Bandarenka of the Maskoŭski District Court of Minsk sentenced Bialenski to one and a half years in an open correctional facility under Part 1 of Art. 342 of the Criminal Code, “active participation in group actions that grossly violate public order”. Bialenski was released in the courtroom to await an appeal hearing.

According to the indictment, Bialenski joined a group of protesters who grossly violated public order on Masherau Avenue in Minsk. The defendant allegedly shouted slogans, clapped his hands, obstructed public transport and repeatedly refused to obey police officers. He also allegedly called on other demonstrators to commit illegal acts.

As a result, at least five bus routes, four trolleybuses and two trams were stopped.
