MOSCOW. Aug 29 (Interfax) - Ukrainian filmmaker Oleh Sentsov, who had been convicted of terrorism, was transferred to Moscow's Detention Facility No. 2, also known as the Butyrskaya prison, an informed source told Interfax.
"Sentsov has been transferred from a penitentiary in the Yamal-Nenets Autonomous District, where he was serving time, to the Butyrskaya prison in Moscow," the source said.
Another source told Interfax that the Ukrainian convict might have been transferred to Detention Facility No. 2 of the Federal Penitentiary Service, i.e. Lefortovo.
There are two Detention Facilities No. 2 in Moscow, one of which operates under federal jurisdiction and the other is operated by the Moscow branch of the Federal Penitentiary Service, the source said.
The media said earlier that the filmmaker, whose release from prison had been urged by the Ukrainian authorities and a number of international organizations, was included in the number of captives to be exchanged between Russia and Ukraine.
"He has been transferred to Moscow within the framework of the ongoing exchange process," the source told Interfax.
In August 2015, the North Caucasus District Military Court in Rostov-on-Don sentenced filmmaker Oleh Sentsov from Simferopol, who was detained in Crimea in 2014, to 20 years in a high-security penitentiary for plotting a terror attack.
