The main accused, Shubham, along with Bobby and Pramod, have been arrested in connection with the murder of Puranlal alias Sagar, a resident of Bithra village. "The arrested accused had an old rivalry with the deceased. The trio kidnapped him on Monday and, with the help of another accused, strangled him to death. The accused later dismembered the body to avoid its identification," Superintendent of Police (SP) Avinash Pandey said. The victim's family claimed Shubham had threatened Sagar a week prior, asking whether he would play the "Holi of colors or blood." According to the police, Sagar's body appeared to be 3-4 days old.
