Oleg was arrested in October 2021 in connection with a criminal case opened under the article "organizing and preparing actions that grossly violate public order, or active participation in them," and was remanded in custody pending trial.
On February 1, 2022, he was convicted of participating in a post-election protest that took place on August 9, 2020, in Zhlobin and sentenced to restricted freedom and placement in an open correctional facility.
Oleg was granted a third-degree disability. Therefore, on May 25, 2022, the court replaced his prison sentence with a more lenient one: house arrest. The court hearing was postponed three times.
