A federal judge in New York City sentenced a neo-Nazi from the country of Georgia to 15 years in prison for multiple crimes tied to a terror plot targeting Jewish children.

Prosecutors said 22-year-old Michail Chkhikvishvili was a leader of the Maniac Murder Cult, an international white supremacist organization rooted in neo-Nazi ideology.

Authorities said Chkhikvishvili, who went by the nickname “Commander Butcher,” recruited followers to carry out mass casualty terror attacks in New York City.

Investigators said he circulated a manifesto titled the “Hater’s Handbook,” which urged readers to carry out school shootings and other violent acts “for the white race.”

According to prosecutors, one of the individuals he attempted to recruit for the attacks was actually an undercover FBI agent.

Officials said that in November 2023, Chkhikvishvili devised a New Year’s Eve terror plot in New York City in which the attacker would dress as Santa Claus and hand out poisoned candy to racial minorities.

By January 2024, prosecutors said he changed the plan and instructed the undercover FBI agent to target Jewish schools and Jewish children in Brooklyn using poison.

Court filings said Chkhikvishvili provided the agent with detailed guidance on producing deadly toxins and gases, including ricin.

Chkhikvishvili was extradited to the United States from Moldova last year.
