On 24 February 2022, the day Russia launched its full-scale invasion of Ukraine, Aliaksandr was detained in Zhodzina. According to the prosecution, since the autumn of 2020 he had been posting calls for protests in local opposition chats, and on that day he suggested gathering near the Green store to speak out against the war. After his detention he was made to record a "repentance" video.
In May 2022, Aliaksandr was found guilty in a criminal case brought under the article "Organisation and preparation of actions grossly violating public order, or active participation in them" and sentenced to imprisonment in a penal colony.
According to human rights defenders' calculations, he was released in January 2024 after serving his full sentence.
