The Russian Investigative Committee said Tagiryanov's gang is responsible for at least 20 killings and "dozens of other serious crimes, committed mostly in order to extort money from businessmen," spokesman Vladimir Markin told RIA Novosti.
Tagiryanov's gang first emerged in the 1990s in the Volga city of Naberezhnye Chelny. Government officials cracked down on many of the group's members in 2003 and by 2007 most members had been sentenced to lengthy prison terms, RIA Novosti said.
Tagiryanov and two top lieutenants, Albert Khuzin and Oleg Datsko, stood trial together recently. Datsko also received a life sentence; Khuzin will spend 25 years in prison.
