A 22-year-old Georgian national who called himself Commander Butcher was sentenced to 15 years in federal prison this week after federal prosecutors said he led an international violent extremist group, distributed instructions for making bombs and ricin, and planned a mass casualty attack targeting Jewish communities in Brooklyn. The Department of Justice announced the sentencing on May 13. Michail Chkhikvishvili, who also went by Mishka and Michael, was sentenced by U.S. District Judge Carol Bagley Amon in the Eastern District of New York. Chkhikvishvili had pleaded guilty in November to soliciting hate crimes and distributing information about manufacturing explosives and the deadly poison ricin.
