 | Semion Yudkovich Mogilevich is a Ukrainian-born, Russian organized crime boss, believed to be the "boss of bosses" of most Russian Mafia syndicates in the world. Mogilevich is believed to direct a vast criminal empire and is described by the FBI as "the most dangerous mobster in the world." He has been accused by the FBI of "weapons trafficking, contract murders, extortion, drug trafficking, and prostitution on an international scale". He is most closely associated with the Solntsevskaya Bratva crime group. |  Alexander Litvinenko, shortly before his assassination, claimed that Mogilevich had a "good relationship" with Vladimir Putin since the 1990s. |
 | In 1997 and 1998, Canadian journalists exposed the presence of Mogilevich and others associated with the Russian Mafia behind YBM Magnex International Inc., a public company trading on the Toronto Stock Exchange. On May 13, 1998, the FBI and police raided YBM's headquarters. Shares in YBM, which had been valued at $1 billion on the TSX, became worthless overnight. In 1999 officials from YBM Magnex admitted in a U.S. court that the company was created for the sole purpose of committing securities fraud. Until 1998, Mogilevich participated in a US$10 billion money laundering scheme through the Bank of New York. Mogilevich was also suspected of participation in large-scale tax fraud, where untaxed heating oil was sold as highly taxed car fuel. The scam resulted in massive tax losses for various countries in central Europe |  |
 | In spite of the various warrants issued against him, he still lives freely in Moscow, according to the FBI. Mogilevich and his top associates stopped travelling to the west in the late 1990s. A number of Mogilevich associates have dealt directly with Donald Trump and his organization. See ---> IRNET |  |
