Mikhail Khodorkovsky, the former boss of Yukos oil company convicted of embezzlement and tax fraud, was delivered to prison colony number seven near the town of Segezha in Russia's northwestern Karelia region, a source in the penal system administration said on Friday.
Khodorkovsky's return to the penal system follows an appeal against his sentence and a second trial in Moscow.
He was sentenced to an additional six years on top of his initial eight year sentence by a Moscow court in December 2010, later reduced by one year. He is now due for release in 2016.
He served the initial part of his first sentence in Russia's remote Chita region near China and Mongolia, 6,000 km from Moscow.
Khodorkovsky’s business partner Platon Lebedev, serving a 13-year sentence for oil embezzlement and money laundering, has arrived in Penal Colony 14 in the Arkhangelsk Region in northwestern Russia, a law enforcement source reported.
“Lebedev has arrived in the Arkhangelsk Region. There is no information yet whether he will serve his term here or will be transported to another region,” the source said.
The regional penitentiary authority was unavailable for comment.
Lebedev served the initial part of his first sentence in the Yamal-Nenets Autonomous Area in northwestern Siberia.
