A bullet riddled body of a youth was found here late last night, police said on Sunday.
Police said the youth was kidnapped on Saturday morning.
According to official sources here the deceased, Enoch Tangkhul (30), was kidnapped by some unknown gunmen on Saturday.
Meanwhile, NSCN(K) had claimed to have killed the youth alleging that he was the informer of their rival NSCN-IM.
They have also warned the Tangkhul tribe that the killing was in pursuance of their "Quit Notice" issued to the community to leave the state.
"Tangkuls intrusion into Naga political has brought about irreparable setbacks in our national aspirations,"NSCN(K) sources said.
The NSCN(K) sources further said the Tangkhul community was being asked to leave the 'Naga country' to 'Unite Nagas under one banner and live as one people and nation'.
