Maoists walked away with weapons of the killed policeman.

The death of Choubey, who had earned reputation as one of the sharp and bold police officers in the state, has shaken up the police force. All high-ranking officials, including Director General of Police Vishwaranjan and Home Minister Nankiram Kanwar, rushed to the attack site.

Several injured were admitted to the Rajnandgaon district hospital while a few others were airlifted to state capital Raipur for advanced medical attention.

Insurgents had killed two DF personnel in another incident in the same area Sunday morning. Choubey was leading his reinforcements to that attack site when his convoy was blown up mid-way.

Chief Minister Raman Singh cancelled his trip to Nagpur scheduled for Sunday afternoon after the attack.

After the ultras came to control Lalgarh area in West Bengal, the central government had banned the Communist Party of India (Maoist) last month.
