Dmitry was a witness in the case of Brest political prisoners and bloggers Sergei Petrukhin and Alexander Kabanov, who were sentenced to three years in prison in April 2021. As he told Brest human rights activists, the criminal case against him was opened for refusing to answer questions from the judge hearing Petrukhin and Kabanov's case because the judge had failed to present his official identification. In September 2021, Dmitry was found guilty of "refusing or evading testimony" and sentenced to arrest.
He was released in February 2022, having fully served his sentence.
In December 2024, Dmitry was convicted again under the article "organizing and preparing actions that grossly violate public order, or active participation in them" and sentenced to imprisonment in a penal colony.
According to human rights defenders, he was released in the spring of 2026 after fully serving the sentence imposed by the court.
