Sohan Mandavi (28), the ex-deputy sarpanch of Burgum village under Kodenar police station limits, was killed in the forests near the village, Bastar Superintendent of Police Ajay Yadav said.
The incident came to light this morning when some villagers informed police that the blood-stained body of Mandavi was found on a road, nearly 3 kms away from his native village, the SP said.
"Soon after getting the news of the incident, security forces were rushed to the spot," he said.
Preliminary investigation suggested that naxals suspected Mandavi of being a police informer, he said.
A search has been launched in the forest to nab the attackers, he added.
