The Prosecutor-General's Office said evidence indicates some connection between former Yukos officials, including Nevzlin, and "crimes against the lives and health of [Russian] citizens."
Nevzlin was a senior official at Yukos. Former Yukos CEO Mikhail Khodorkovsky at one time gave Nevzlin a controlling 60-percent stake in the embattled oil company.
Yukos has since been driven into bankruptcy by huge back-tax claims and Khodorkovsky is in prison on tax-evasion and fraud convictions. Nevzlin fled the country and is now an Israeli citizen.
Russia is seeking to have Nevzlin extradited to answer charges. Nevzlin was briefly detained by U.S. customs officials on December 24, but was released due to the absence of a Russian-U.S bilateral extradition agreement.
