On the evening of 9 August 2020, Yauhen went to the Stele in Minsk, where people who disagreed with the election results were gathering, and then ended up on Masherau Avenue together with the crowd. That night he was detained with the use of force and held at the Akrestsina detention center until 14 August.
Almost a year later, on 5 August 2021, Yauhen was detained again and held in custody until the trial.
In November 2021, Yauhen was found guilty in a criminal case opened under the article "Organisation and preparation of actions that grossly violate public order, or active participation in them" for taking part in that protest, and was sentenced to restricted freedom without referral to an open-type correctional facility. He was released in the courtroom.
In November 2024, an in absentia court hearing was held under special proceedings to consider a harsher type of punishment. The outcome of the hearing is unknown.
