Maoists set afire two tractors and a road-making machine in Pajjibali village under Muniguda block here on Friday night.
The machine and vehicles were used for road construction works in the village.
A group of 20 to 25 armed Maoists including three women cadres arrived at the spot and set ablaze the vehicles owned by Parshuram Sahu, a contractor undertaking road works from Bhursikhamar to Panimunda village under Pradhan Mantri Gram Sadak Yojana (PMGSY).
They left behind posters which read that no road work should be carried out in the area using machines and locals should be employed to do the work. Workers were not at the site when the incident took place.
Following the incident, Rayagada SP Rajesh Pandit and other officials visited the spot. He suspects involvement of Maoist leader Nikhil in the incident.
