A policeman was hacked to death by Maoists at a weekly market in insurgency-hit Bijapur district, a police official said here on Sunday. The incident occurred around 2 pm when assistant constable Chaitu Kadti went to the market in Mirtur village along with his family members, he said. A 'small action team' of Naxals (typically comprising four to five cadres) suddenly stabbed Kadti with knives, killing him on the spot, and fled, the official said. The rebels did not harm the family members of Kadti, who was posted at Mirtur police station, he said. On getting information about the incident, a police team rushed to the spot and sent the body for postmortem, the official said. A search operation was underway to nab the assailants, he added.
