Sergei Shemkevich, the former general director of Tomskneft, the largest subsidiary of the now bankrupt Yukos oil company, is accused of misappropriating 5.93 billion rubles ($229 million) and laundering the illegal receipts.
"The Basmanny Court of Moscow has met the motion from the Prosecutor General's Office and extended the custody term for Shimkevich until December 16," the spokesman said.
Shimkevich's arrest was sanctioned by the Basmanny Court of Moscow January 18 of this year following a request from the Russian Prosecutor General's Office.
Shimkevich was detained January 16 in Siberia's Tomsk Region while serving as a deputy in the regional legislature. He was deprived of his mandate following the sanction for his arrest.
