According to Eesti Ekspress, Estonian Internal Security Service detained a local teenager they alleged was one of the leaders and recruiters for the group, operating under the nickname "Commander" or "" ("Warlord"). He had instructed others how to build bombs, spoke about planning attacks and encouraged members to take part in the paramilitary training. However, the authorities could not legally arrest him due to his minor status, and being not criminally liable. His alleged status in the group was also disputed by Eesti Ekspress. In a published picture, the boy can be seen wearing a skull mask and holding a pistol, taking part in the firearms training organized by Kaalep, who is also believed to have taken part in the group's chats under the pseudonym "Kert Valter".
