LUCKNOW, Sept. 2 -- The explosion that ripped through a house in Gudamba's Behta area on Sunday was due to the storage and mishandling of firecrackers, police said, citing preliminary investigation. Also, five people---including one of the deceased---have been booked in the case. All of them are relatives. According to the FIR lodged by sub-inspector Santosh Patel, who's in charge of the Behta police outpost, the explosion occurred around 11:55 am and rocked a residential area in Behta. Local police, fire brigade teams, and ambulances rushed to the site and rescued seven people trapped under the collapsed structure and adjoining houses. Doctors at a nearby hospital declared two of them-Alam (50), and his wife Munni (48)-dead on arrival. Five others-Irshad (22), the couple's son; Nadeem (24); Zaid (35); Imran (32); and Noorjahan (25)-were hospitalised with injuries. The police named five people-Alam (deceased), Sheru alias Wasir, Shoaib and Tinu alias Ali Ahmad and his brother Ali Ahmad-as accused in connection with the illegal firecracker operation. A case has been registered under Sections 105, 110, and 3(5) of the BNS along with Sections 3, 4, and 5 of the Explosives Act, 1908.
