Maoist militia members allegedly set ablaze a road-roller at the remote Burkankota village in Chintur mandal in the wee hours of Thursday.
A group of militia members owing allegiance to the Sabari Dalam allegedly poured kerosene on a parked road roller and set it afire on the outskirts of the village in the early hours of the day.
The road-roller was stationed near the village for carrying out the road works under the Central government sponsored Integrated Action Plan for Left-wing extremism affected areas, sources said.
The militia members reportedly left behind a letter at the scene of offence demanding stoppage of the road works.
Tension mounted in the area close to the inter-State border with Chhattisgarh following the incident.
