Gleb is the director of the Ikvadrat web design studio in Grodno. On August 10, 2020, he was brutally beaten by security forces and taken to the emergency room with injuries. In August 2021, following a search of his home and office, Gleb was detained. On September 8, it was announced that he had been charged with "organizing and preparing actions that grossly violate public order, or active participation in such actions."
In December of that year, Gleb was convicted of participating in a post-election protest in August 2020 in Grodno and sentenced to restricted freedom and sent to an open correctional facility. While in the correctional facility, Gleb was also tried under the administrative law for "disseminating extremist materials."
In May 2023, a court hearing was held to discuss the issue of replacing the restriction of freedom with imprisonment in a penal colony.
He was released in June 2023, having fully served his sentence as imposed by the court.
