Russian billionaire and Kremlin critic Boris Berezovsky has found dead in his apartment in London at 11 a.m, his son-in-law, Yegor Shuppe, wrote on his Facebook page on Saturday.

      The information about the 67-year-old businessman's death is still very controversial. According to some sources, there were no signs of violent death on Berezovsky's body. At the same time, his attorney, Alexander Dobrovinsky, says Berezovsky is reported to have commited suicide, but this information is also not proved.

      The mysterious death came seven months after Berezovsky lost a $5.6-billion court battle with rival oligarch and Chelsea Football Club owner Roman Abramovich.

      Berezovsky was born in 1946 in Moscow. In 1968 he graduated from the Moscow Forestry Engineering Institute and worked as an engineer, from 1969 till 1987. Berezovsky made his fortune in Russia in the 1990s when the country went through privatisation of state property and "robber capitalism". He left Russia in 2000 over a money laundering scandal with Aeroflot airlines and has been the subject of an extradition by Russia while appearing on its most wanted list since 2001 on charges of fraud, money-laundering and attempted violent power takeover.
