London, England -- British police say Boris Berezovsky, a self-exiled former Russian oligarch who had a bitter falling out with Russian President Vladimir Putin, has been found dead in southeast England.
Thames Valley police say his death is being treated as unexplained.
Police would not directly identify Berezovsky, but when asked Saturday about him by name they read a statement saying they are investigating the death of a 67-year-old man at a property in Ascot, a town 40 kilometers (25 miles) west of London.
A mathematician-turned-Mercedes dealer, Berezovsky amassed his wealth during Russia's chaotic privatization of state assets in the early 1990s.
After falling out with Putin, he sought political asylum in Britain in the early 2000s.
