In October 2021, Uladzislau was detained at Minsk-Arena before a hockey match: during a search, a passport in a cover with the Pahonia coat of arms was found on him. He was taken to the district police department, and the next day a court sentenced him to administrative arrest for allegedly disobeying police officers.
Later, a criminal case was opened against Uladzislau. According to the prosecution, in August 2020 he took part in a march in Minsk: he walked out onto the roadway, shouted slogans and clapped his hands. He was also charged with possessing 0.15 grams of hashish.
In March 2022, he was found guilty in a criminal case initiated under the articles "Organisation and preparation of actions that grossly violate public order, or active participation in them" and "Illegal trafficking of narcotic drugs", and sentenced to imprisonment in a penal colony.
Released on September 20, 2023, after fully serving the sentence imposed by the court.
