- The enigmatic leader of the Red Mafia is a 52-year-old Ukrainian-born Jew named Semion Mogilevich. He is a shadowy figure known as the Brainy Don--he holds an economics degree from the University of Lvov--and until now, he has never been exposed by the media. But the Voice has obtained hundreds of pages of classified FBI and Israeli intelligence documents from August 1996, and these documents--as well as recent interviews with a key criminal associate and with dozens of law enforcement sources here and abroad--describe him as someone who has become a grave threat to the stability of Israel and Eastern Europe.
- He was twice jailed in the seventies for minor currency offences. Mogilevich is a self-confessed lifelong and instinctive capitalist. While in the gulags his network included hardened criminals, relationships that have endured to this day, the most notorious is with Sergei Mikhailov, reputedly head of Moscow's much feared Solsnetskaya Gang
Mogilevich was arrested in Moscow in January 2008.
