The jawan received bullet injuries in the face-off that occurred in the restive Lingapur forest under Basaguda police station limits late last evening, a senior police official said.
A team of paramilitary forces was mobilised from Bijapur for an anti-Naxal operation in the interiors of Basaguda in south Bastar.
When they reached Lingapur forests, around 450 kms away from the state capital, the Naxals opened indiscriminate fire on them leaving a constable injured, he said.
However, the rebels retreated into the dense forests when the forces retaliated, the official said.
Soon after being informed, reinforcement was rushed to the spot and combing operation has been launched in the region to nab the attackers, he said.
