The skirmish took place in the forests under Maraguda police station limits during an anti-naxal operation in the region by the paramilitary forces, Sukam Additional Superintendent of Police Santosh Singh told PTI.
A squad of the 217th batallion of Central Reserve Paramilitary Force launched an operation late this evening after getting an information about digging of a road by ultras near the force's Maraiguda camp, located around 450 kms away from the state capital, Singh said.
During patrolling, a group of armed cadres opened indiscriminate firing on the security personnel leaving one of them dead and another injured, he said.
"The killed jawan was identified as Ashok Kumar Jat of constable rank," theASP said.
Soon after getting the news of the incident, additional force was rushed to the spot, and the injured and the body of the jawan were retrieved out from the forest through helicopter, he said.
A manhunt has been launched in the region to nab the attackers, he added.
