A Moscow City Court on April 8 rejected an appeal in the case of Viktor Ishayev, the former governor of Russia's Khabarovsk region who faces embezzlement charges.
Ishayev was calling for the reversal of a March 28 ruling by the Basmanny District Court that placed him under house arrest.
Ishayev’s lawyers had called for Ishayev to be released on 15-million-ruble bail, or about $230,000.
Russia's Investigative Committee on March 28 accused Ishayev and several other unnamed people of embezzling money via fraudulent activities from the state-oil company Rosneft.
The Khabarovsk regional governor's spokeswoman, Nadezhda Tomchenko, told reporters that the offices of the regional administration in the city of Khabarovsk had been searched that same day by officers of the Federal Security Service (FSB).
Ishayev, a member of the ruling United Russia party, was a vice president at Rosneft from 2013 to 2018.
He governed the Far Eastern Khabarovsk region from 1991 to 2009.
In April 2009, he was appointed the presidential envoy to the Far Eastern Federal Territory and served as Russia's minister for the development of the Far East in 2012 and 2013.
