Twelve of the 16 Naxalites killed in an encounter in Chhattisgarh's Gariaband district have been identified as dreaded ultras carrying a cumulative bounty of Rs 3.13 crore, including a central committee member of the outlawed movement, a police official said. Among them was Chalpathi alias Jairam, a member of the central committee and Odisha state committee of the Communist Party of India (Maoist), who had a collective bounty of Rs 90 lakh on his head in Chhattisgarh, Odisha and Andhra Pradesh. It was the first time someone from the central committee, the main governing body of the proscribed outfit, has been eliminated in an encounter in Chhattisgarh. The encounter, which lasted three days, involved personnel from E-30 (a Gariaband district police unit), Central Reserve Police Force (CRPF), its elite unit CoBRA (Commando Battalion for Resolute Action) and Odisha police's Special Operation Group (SOG).
