Moscow: Russian prosecutors say they are lobbying Interpol to put Russia's once richest man Mikhail Khodorkovsky on a wanted list.
The country's top investigative body last year declared Khodorkovsky arrested in absentia.
The Kremlin critic and former oil tycoon has lived abroad since 2013 when he was pardoned after serving 10 years in a Russian prison. Investigators accuse Khodorkovsky of involvement in the 1998 murder of a Siberian mayor.
The prosecutor general's office said on Monday that Russia would supply Interpol with more information to back up an arrest warrant for Khodorkovsky that Interpol previously rejected.
The pressure mounted on Khodorkovsky last year after he emerged from the shadows and accused President Vladimir Putin of usurping power and leading Russia to ruin.
