Khordokovsky's prison near Petrozavodsk

Prison service officers block the road at the prison where Mikhail Khodorkovsky was kept in Segezha, near the city of Petrozavodsk, on Dec. 20. Russia’s once richest man Mikhail Khodorkovsky, the arch rival of President Vladimir Putin, has been released from prison after a decade behind bars, his spokeswoman told the Associated Press on Friday. Khodorkovsky spent 10 years in prison on politically tinted charges of tax evasion and embezzlement. Source: AP
