The operation, conducted by paramilitary CRPF along with state police in the Chintagufa-Bheji area of the district, saw an exchange of fire between the two sides when the forces were out for an anti-Naxal operation.
The forces recovered two local guns called 'bharmar', 53 rounds of different ammunition, Improvised Explosive Device (IED) weighing 5kg and some other material from the spot, a security official here said.
The IEDs were later crippled.
