One Shakeera Begum (35) and her son Abbas were charred to death in the fire mishap, while some others somehow managed to escape, the police officer said.
As per the preliminary investigation, the fire could have either caused due to a short-circuit or sparks generated from cooking from an adjoining room, the inspector said.
