MOSCOW (AP) -- Russia's top investigative agency has accused exiled tycoon and former prisoner Mikhail Khodorkovsky of involvement in the 1998 killing of a Siberian mayor, accusations he has dismissed as sham.
The Investigative Committee said Friday a probe has revealed that Khodorkovsky was involved in the slaying of Vladimir Petukhov, the mayor of Nefteyugansk, the town where Khodorkovsky's oil company, Yukos, was headquartered at the time. The authorities in the past said they suspected Khodorkovsky of involvement, but failed to produce any proof.
Khodorkovsky has repeatedly denied the accusations.
Khodorkovsky, once Russia's richest man, spent 10 years in prison on tax evasion and embezzlement charges widely seen as punishment for challenging President Vladimir Putin's power. Since his 2013 release, Khodorkovsky has continued to oppose the Kremlin from exile in Switzerland.
