The doctors have reportedly claimed that the child died of heart attack.
Reportedly, the Telangana Police said the child returned to the school after the school hours winning third position among the sixty students who participated in an inter-school singing competition held at the Mandira Hills area in Hyderabad.
A hospital official said the student had started responding to treatment. He was then shifted to another hospital for better treatment, but was later declared dead.
Achyut Rao, the spokesperson for the Balala Hakkula Sangham (APBHS), an NGO working for child rights, has demanded for a strict action against the school management for Adarsh's death.
"The actual reason for death will be known only after the post-mortem report," Rao told ANI.
"This is, however, absolutely wrong and we demand an action to be taken against the school management," he added. (ANI)
