The skirmish took place between a team of District Reserve Group (DRG) and ultras in the jungles of Katekalyan police station area, Dantewada Superintendent of Police Kamlochan Kashyap told PTI.
While undertaking an anti-naxal operation in Katekalyan, located 450 kms away from the state capital, security forces spotted a group of armed cadres between Lakhapal and Turrempara villages following which a gun-battle broke out between both the sides, the SP said.
After the ensuing gunfight that lasted for around an hour, naxals escaped into deep jungles.
Further details are awaited as security forces are yet to reach back to their camp, the SP said.
