Silchar, Aug. 3 -- A 15-year-old girl was found dead at her home near National Highway-6 in Assam's Hailakandi district, with her family alleging she was raped and murdered, police said on Sunday, adding that four people have been detained for questioning in the incident. Senior superintendent of police (SSP), Hailakandi, Amitab Sinha, said police have registered a case in connection with the incident, which took place on Saturday night. Though the family members alleged that the girl was sexually assaulted before being murdered, the SSP said the allegations are yet to be established medically. "The family members are claiming it [rape], but we are waiting for the post-mortem report to draw any conclusions. We are investigating the matter, and four persons are currently being questioned," Sinha said. The incident took place in the Aloichora area under Katlichera police station at 11pm on Saturday. The victim's family said they were attending a feast at a nearby relative's house at the time. "It's a neighbourhood where many members of the same extended family live together, and her family members were not far when the incident took place," the SSP said. "She was there at the feast too, but after an argument with a cousin, she left for home at 10.30pm. But when we reached home around an hour later, it was a horrible scene," her mother said, adding that her body was found lying on the floor, almost unrecognisable. The victim's sister alleged that the attackers used utensils and other objects to mutilate the body. "Her face was smashed, her head was bludgeoned with a heavy object, and some rod-like object was inserted into her private parts," she said. Police said they received the information around 12.30am, and recovered the body on Sunday morning after protests by family and neighbours. Locals initially refused to hand over the body to the police, but later the body was transported to Silchar hospital for autopsy, police said....
