Marina, a confidant of presidential candidate Svetlana Tikhanovskaya, was detained on July 9, 2021, as part of a "KGB operation to purge radicals" and placed in pretrial detention on charges of financing the activities of an extremist group.
On November 10, 2021, the charge was reclassified to a more lenient charge—"training and preparing individuals to participate in actions that grossly violate public order, as well as their financing or other material support." After this, she was placed under house arrest.
On November 11, 2022, the court sentenced Marina to one and a half years of imprisonment in a general regime penal colony, taking her into custody in the courtroom.
She was released in June 2023, having fully served her sentence as imposed by the court.
