Stanislav was detained upon returning to Belarus from Poland, where he had moved more than a year earlier. He came home in late 2023 to spend the holidays with his family, but was arrested in connection with a criminal case opened after protests on August 10, 2020, in Brest against the falsification of the presidential election. Stanislav was convicted of participating in “mass riots.”
In a pro-government confessional video published, he says that he "participated in protests and went out onto the roadway." The recording shows that Stanislav's face is scratched, although no such damage was visible when he was detained.
