Police seized some guns and naxal material from the spot.
Notably, police found some horses in the camp, which indicates the presence of a senior cadre in the area, an official said.
The skirmish occurred around 2 pm at the border of Gadchiroli and Narayanpur districts in the Abujhmad area, considered a bastion of the ultras, between the Anti-Naxal Squad of the police and naxlaites, he said.
"The ultras fled the spot after realising that the police are closing in on them," the senior official said.
"Police also found six horses, items of daily use, and some naxal literature. Mostly, senior cadres use horses in the Abuzhmad forest area. The presence of horses indicates that a very senior Maoist like Bhupati might be operating in this area," the official added.
