At a special sitting, Justice K.Kalyanasundaram directed the Hospital and Police authorities to preserve the body at the same mortuary till December 29.
The petitioner said police had registered a case of suicide inspite of him lodging a complaint that the boy, studying in the 11th standard, was murdered by school authorities.
He alleged that police was supporting the school and said he had no faith in the investigation of local police and sought a direction to transfer the probe to CBI.
He also prayed for a re-postmortem and an interim stay on all further proceedings of the case on the file of the Perambalur Police Station.
