Oleg Sentsov is a Ukrainian filmmaker, Euromaidan activist and native of Crimea. After the Russian annexation of Crimea, he became an active opponent of the occupation. In May 2014, he was arrested by the Russian security service, charged with planned terrorist attacks and transported to Moscow. After over a year in custody, he was sentenced to 20 years in prison, despite the fact that the testimonies were given under duress and evidence was insufficient. Sentsov never pled guilty.
