Leaking gas caught fire and the house wife tried to extinguish the fire by turning upside down of the cylinder and rubbing over the mud floor. She also put a blanket and poured soap water to extinguish fire unsuccessfully.
The cylinder burst and metal fragments pierced into the bodies of the neighbouring children gathered around the spot. Police booked case against the house wife for causing injuries due to negligent act.
