KARNAL: The family members of a six-year-old dalit boy have alleged that their kid, who was locked for several hours in his school bathroom for failing to turn in his homework, suffered a trauma that created severe health complications leading to his death more than a month after the punishment was meted out.The parents of Pankaj Singh told reporters after his death on Saturday night that he had been sick since he was incarcerated in the washroom in his Karnal school and never recovered . Jaiveer and Reena Singh alleged that their child was found by his elder brother Sagar lying unconscious in the bathroom. Ever since, he was unwell. "After remaining ill for over 55 days, Pankaj died on Saturday night," said the boy's paternal uncle Mahipal Singh.The district administration said it is yet to receive any complaint from the parents of the boy and are thus unable to take action against the teacher or the school authorities. Pankaj was locked by his teacher in a bathroom for several hours on December 27 for failing to complete his homework."The boy remained in a state of shock due to the inhuman treatment given to him by the teacher. His relatives said that after being treated, Pankaj could attend school for just one day before plunging into depression again," said Mahipal Singh. School manager Bablu Rana said the child was suffering from some disease and ultimately succumbed to it, which is denied by Pankaj's parents . When contacted, deputy commissioner Neelam Kasni said the administration has not received any complaint from the parents.
