Three rebels, dressed as civilians, attacked Benjam with axes near his house in Kolengpara locality of the village, located around 350 kms from the state capital, he said.
The reason behind the killing was not yet known.
But, prima facie it seems the Naxals suspected that Benjam was a police informer, the official said.
