The billionaire former head of Russian oil company Russneft is hiding in London from the Russian police, who wants to arrest him for tax evasion, Russia’s ministry of interior said on Thursday.

Mikhail Gutseriyev, whose personal fortune is estimated at around $2.6 billion, has countered the tax evasion charges by saying the accusations are false & designed to imprison him so that prokremlin businessman can buy Russneft cheaply. His last previously known locations was in Turkey. An official of British embassy declined to comment.
