Aliaksandr worked as a builder. In February 2021, a criminal case was opened against him for insulting a representative of the authorities: it was based on his comment in a Telegram channel about the head of the Gomel riot police, Mikhail Domornatsky. In court, Aliaksandr explained that he knew Domornatsky personally, disliked him and had challenged him to a duel.
The trial began in late June 2021; the prosecution asked for three years of restricted freedom with referral to an open-type correctional facility. During the trial he was under a travel ban, and after his final statement he disappeared, and in early July he was put on the wanted list. His further fate is unknown.
