MOSCOW, July 7 (RAPSI) – The Lefortovsky Court in Moscow on Monday extended the arrest of Ukrainian film director Oleg Sentsov, who was detained in Crimea, until October 11, RAPSI reports from the courtroom.

Sentsov was one of the four alleged members of the Right Sector ultra-nationalist group detained by Russia’s Federal Security Service (FSB) in May on suspicion of plotting attacks in Simferopol, Yalta and Sevastopol. The FSB said the suspects had confessed that the Right Sector was involved in planning attacks “aimed at destabilizing the sociopolitical situation in Crimea.”

The request to extend Sentsov’s arrest by three months was filed by the investigators. Sentsov has already been in detention for two months.

Sentsov denies all charges against him. He said he had never been a member of the Right Sector and that the investigators had no evidence against him other than the testimony of the other detainees, who were promised sentence mitigation. He said the charge of exploding the Eternal Flame monument was insulting, because he considers that monument untouchable.

In late June, Oscar-winning film director Nikita Mikhalkov signed an appeal which Serhii Trymbach, president of Ukraine’s National Union of Filmmakers, sent to Russian President Vladimir Putin, asking him to help release Sentsov.
