As part of its probe into the murder of Pradyuman Thakur, the Gurgaon Police had questioned the juvenile apprehended by the CBI — “as a witness”. According to police, the boy was the first responder to the crime and was not treated as a suspect as “there did not appear to be a motive”. Sources told The Indian Express that hours after the incident, police had questioned teachers, students and staff to ascertain the exact sequence of events. “The apprehended 16-year-old was also questioned as he informed the gardener and teachers on finding the body inside the washroom,” police sources said.
