"Yes, his (Sentsov’s - Ed.) health went downhill. He has heart issues - cardiac insufficiency. He also suffers from rheumatic disease of the lower limbs, problems with the liver and kidneys since his blood changed due to the hunger strike. Accordingly, he was prescribed certain medications, glucose infusions, food mixtures. Based on this, in line with the doctors’ opinion, he takes certain drugs that are being prescribed to him," Dinze said.
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 cousin-sister Natalia Kaplan said March 16, 2018 that her cousin 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.
