"I saw the body. There were some injury marks and cotton on his private parts. The principal has been threatening me since the beginning saying that keeping quiet will be good for me...," Ramheet Meena, the child's father, said, as he renewed the demand for a CBI probe.
The aggrieved father also demanded that the licence or registration of the school be cancelled.
Divyansh was found dead last Saturday in the reservoir under the amphitheatre of the school located in South Delhi. The initial post-mortem report had suggested he died of drowning and no external injuries were found.
Principal Sandhya Sabu had claimed that Divyansh was a "hyperactive" child who had "tendency" of running away from the classroom.
"Police have not taken any action. Those arrested were given bail immediately instead of being sent to remand. I have raised 25 questions to the police and they are not responding to my questionnaire," he added.
