The assailants had opened indiscriminate fire from sophisticated weapons, leading to the civilians' deaths, the probe agency said.

The NIA, which had registered a case on February 9, found during the investigation that Lunminsei Kipgen was actively involved in the attack, which was part of the ongoing ethnic unrest and violence in the northeastern state.

Previously a cadre of the Kuki militant outfit KNF(P), he joined another Kuki militant organisation -- the United Kuki National Army -- during the current spate of violence and participated in the killings, it added.
