He was detained by police on October 19, 2023. Following his arrest, he served two administrative arrests of 15 days each. Human rights activists are aware that the second sentence was imposed on November 3 by the Central District Court of Minsk. At that time, Judge Yuliana Shcherba found 63-year-old Marchenko guilty of "disseminating extremist materials" (under Part 2 of Article 19.11 of the Code of Administrative Offenses).
Alexander's trial began on March 25, 2024, in the Minsk City Court.
On June 4, 2024, Alexander's appeal was heard. The appeal was dismissed.
On March 19, 2026, he was pardoned after another visit to Minsk by US President Donald Trump's special representative, John Cole (among a group of 235 prisoners left in Belarus).
