Alexey was arrested on July 27, 2021, in connection with a criminal case under the article "organizing and preparing actions that grossly violate public order, or actively participating in them." Earlier, on election day, August 9, 2020, he was detained at a polling station and beaten at Okrestina. On August 16, he participated in a march and showed bruises from the beating—protesters had written "You can't kill everyone" on his back, a moment filmed near the KGB building. He also participated in the March on October 25, 2020, where he climbed onto the roof of his car with a white-red-white flag and shouted "Long Live Belarus."
In September 2021, Alexey was convicted of participating in protests and sentenced to imprisonment in a penal colony.
He was released in May 2022, having fully served his sentence.
