According to police reports, 300 Naxal fighters initially attacked a convoy of the paramilitary Central Reserve Police Force (CRPF) in the Talmetla area as they were returning from an operation. The Naxals were hiding when the 74th Battalion of the CRPF reached Kalapathar near Chintagufa in Sukma.
The attack was condemned by the then Home Minister of India P Chidambaram saying it showed the "savage nature" of the Maoists.

The Maoist leader Gopal stated that the attack was conducted as a "direct consequence" to the government's Operation Green Hunt.
Operation Green Hunt is the name used by the Indian media to describe the "all-out offensive by paramilitary forces and the forces of the state" against the Naxalites. The operation is believed to have begun in November 2009 along with five states in the "Red Corridor."
The term was coined by the Chhattisgarh police officials to describe one successful drive against the Communist Party of India (Maoist) in the state.
