Semion Mogilevich, AKA "Seva" and called "The Billion Dollar Don" and "The Brainy Don", has been on the FBI's Most Wanted List since 2003. Mogilevich and associates are wanted in connection with dealings in YBM Magnex International Inc.
In 1997 and 1998, journalists exposed the presence of Mogilevich, Sergei Mikhailov and others associated with the Russian Mafia behind YBM Magnex, then a public company trading on Canada's Toronto Stock Exchange (TSE). YBM was fronted by a former Premier of Ontario and other prominent Canadian businessmen.
On May 13, 1998 dozens of agents for the FBI and other U.S. government agencies raided YBM's headquarters in Newtown, Pennsylvania. Shares in the public company, which had been valued at $1 billion on the TSE, became worthless.
In 1999 the BBC television program Panorama first interviewed Mogilevich for a documentary that looks at transnational criminal activities from the street to the boardroom.
