Nagpur: A four-year-old boy was accidentally locked overnight inside his school classroom in Nagpur’s Khaparkheda, sparking panic in his family. Himanshu Bagde, living just half a kilometre from the school, had wandered into the classroom while playing Wednesday, unaware that staff would later lock the premises without checking the rooms, reports Soumitra Bose. When Himanshu did not return home, his father lodged a missing complaint. Police launched a search operation involving multiple teams across the city, but he still could not be traced. The breakthrough came around 10am Thursday when school staff visited the premises. Himanshu was found asleep inside the locked classroom. The boy was immediately reunited with his parents. It was a lucky escape for the boy as it was a school holiday and staff visited the school only to oversee some construction work that was underway.
