The three - a man and his two sons - had left the camp for displaced persons at Kawatika village in Bijni area of Chirang district yesterday, Chirang Superintendent of Police Kumar Sanjib Krishna told PTI.
"They left the camp yesterday afternoon without informing anybody and without any security. Since then they were untraced. Today we found their bodies at Borlangshu village at Chirang district," he said.
The three, belonging to the minority community, had been stabbed to death, he said.
Additional forces have been rushed to the area, where security personnel are still deployed and night curfew is on.
The incident took place after 10 days of relative peace after the violence in Bodoland Territorial Autonomous Districts last month.
