Police probe 'unexplained' death of Russian oligarch Boris Berezovsky

Berezovsky, who fled to Britain in 2000 after a falling out with Russian leader Vladimir Putin, was found dead on Saturday at his home in Ascot, 40 kilometres west of London. Thames Valley police say his death was being treated as "unexplained" and there was no evidence of "third-party involvement".
