After a brief lull, Maoists seem to be again asserting their presence in Balangir district. On Friday morning, people found a poster allegedly written by the Maobadi lal Salam of Chhattisgarh in front of the Rengali panchyat office in Khaprakhol block of the district. The poster criticised the action of the CRPF and the Cobra Battalion. It also warned a few nearby villagers of dire consequences terming them as “police informers”. Police are verifying the poster, said Balangir SP Asis singh to this correspondent, when contacted.
