On 13 September 2021, Aliaksandr was detained for taking part in a human chain during a protest held in Minsk in 2020, and he was held in custody until the trial.
In December 2021, Aliaksandr was found guilty in a criminal case opened under the article "Organisation and preparation of actions grossly violating public order, or active participation in them" and sentenced to restricted freedom with referral to an open-type correctional facility.
According to human rights defenders' calculations, he was released in September 2024 after serving his full sentence.
