PATNA, Dec. 11 -- A Janata Dal (United) activist was on Tuesday night gunned down by unknown assailants in his house in Pirnagar village under Chhourahi police station limits of Begusarai district, police said. The deceased was identified as Nilesh Kumar Mahto, 37. The incident came to light when family members heard gunshot sounds, arrived at the spot and found Mahto's blood-soaked body lying on the ground. He received bullet injuries to his chest, neck and near his eyes. The family immediately informed the police, who took the body into custody. Police officers familiar with the matter, quoting the family members of the deceased, suggested that the murder might be linked to an old personal enmity. A suspect has been detained and is being questioned. Manjhaul SDPO inspected the crime scene and assured the culprits would be nabbed soon. "Nilesh, former block president of JD(U) and recently elected panchayat head, was sleeping in his house at night when the assailants entered, murdered him and fled," said Begusarai SP Maneesh. Deceased's father Rambali Mahto said his son didn't have enmity with anyone. Previously, there was a land dispute with some people in the village, but the matter had been resolved. He, however, claimed that Brajesh Kumar, Jaiprakash Mahto, Rajesh and Ram Pravesh and other men from the neighbouring village fled from the spot brandishing weapons....
