Nikolai was detained in April 2021 in connection with the events of October 18, 2020, during the "Partisan March" in Minsk. He was charged under three articles of the Criminal Code: for participating in mass riots, intentional damage to property, and the threat of violence against security forces. According to the prosecution, he threw stones and asphalt at service minibuses with Almaz fighters, causing material damage. 13 security forces were recognized as victims, but only three appeared in court - in balaclavas and with changed names.
According to human rights activists, he was released in February 2025, having fully served the sentence imposed by the court.
