MOSCOW, February 27 - RAPSI. Former YUKOS top manager Vladimir Pereverzin, who has been released from prison after serving his term, will soon apply to the police to open a criminal case against the Federal Penitentiary Service, he told journalists on Monday.

Pereverzin was sentenced to 11 years in prison in 2007 for the misappropriation and embezzlement of funds and money laundering. The court mitigated his sentence by 2.5 years in May 2010 after the Criminal Code money laundering article was liberalized.

Finally, Pereverzin's sentence was reduced by another 14 months after amendments to the Criminal Code came into force in March 2011.

"I will file a petition with the Investigative Committee to open a criminal case against the prison personnel and Federal Penitentiary Service personnel who delayed my release on parole," he said.

The Russian Legal Information Agency has yet to obtain comments from the Investigative Committee or the Federal Penitentiary Service.

The YUKOS case has been one of the most high profile in Russia in recent years. In the early 2000s, the authorities accused the executives of YUKOS, then the country's largest oil company, of embezzlement and tax evasion. YUKOS then went bankrupt and its assets were transferred to the state-run Rosneft oil company. Many in the West believe the case against YUKOS was politically driven, but Moscow flatly denies the charges.
