The Estonian teen, known as “Commander” to other members of Feuerkrieg Division (FKD), was tracked down in January, Time reports.

A number of group members have been arrested in recent years, including a 21-year-old who was arrested for alleged terror offences in Newcastle last October.

However, “Commander” avoided arrest when caught by officers because he is under 14, the age of criminal responsibility in Estonia.

A spokesperson for the Estonian Internal Security Service said they “intervened” to end the boy’s involvement in the neo-Nazi group.
