Suspected Naxals set ablaze vehicles and a machine engaged in laying a water pipeline in restive Dantewada district, police said on Sunday.
The incident took place late Saturday night in Masenar village where the pipeline was being laid for water supply, a local police official informed.
According to preliminary information, a group of suspected ultras stormed into the site, located about 450 km south from the state capital, and set on fire a JCB machine and a tractor parked there.
On getting information about the incident on Sunday morning, security forces rushed to the spot and launched a combing operation to track down the ultras.
