The boy's father, Varun Thakur, who works as a quality manager with Orient Craft in Gurgaon, accused the school administration of negligence.
Varun said the school administration did not inform him about his son's death initially.
"They told me his health deteriorated suddenly. They did not take care of my son. He could have been saved if he had been taken to hospital in time," he said.
"I dropped him today at around 7:30 a.m. He was happy,"
the grieving father said.
Hundreds of parents and locals gathered outside the school and protested against the school management.
Senior officials of the Gurgaon police intervened to maintain calm.
