"Convicted Oleg Sentsov - a citizen of the Ukrainian Republic – was escorted [to the prison] on Oct. 9, 2017. His case file includes the passport EC 477125 issued on Nov. 12, 1997," says the document sent to the consulate of Ukraine in Yekaterinburg by the Office of the Russian Federal Penitentiary Service in the Yamalo-Nenets Autonomous District under the Ministry of Justice of the Russian Federation.
Russia earlier repeatedly claimed that Sentsov was a citizen of the Russian Federation at the time of his conviction. Namely, the Crimea-born filmmaker was denied access to Ukrainian consular services in 2014 because he had allegedly "automatically" obtained the Russian citizenship after Russia occupied the Ukrainian peninsula.
As reported, Sentsov is serving a sentence in the maximum security labor camp in the Yamalo-Nenets Autonomous District. This prison's inmates are serving sentences for commission of grave and especially grave crimes.
Sentsov was detained by the Russian FSB Security Service in Russian-occupied Crimea in 2014 together with activist Oleksandr Kolchenko. They were brought to Russia and tried in a trumped-up case on charges of organizing acts of terror and arson on the peninsula. On Aug. 25, 2015, Sentsov and Kolchenko were sentenced to 20 years and 10 years in prison respectively. On Oct. 21, 2016, Russia refused to extradite the two Ukrainians to Ukraine, claiming they had automatically acquired Russian citizenship after the annexation of Crimea.
Sentsov’s sister Natalia Kaplan said March 16, 2018 that her brother reported on his failing health in a letter. He in particular said that he is losing his hair and has his teeth crumbling into small pieces.
On May 14, 2018, the fillmmaker said he went on an indefinite hunger strike demanding to release all Ukrainian political prisoners held in Russia.
