Input: The 78-year-old, who has not been named, died in the blaze on Mundy Street, in Derby, on Monday morning. A Derbyshire Fire and Rescue Service investigation concluded the most likely cause of the blaze was accidental due to "smoking materials". A man was also taken to hospital for minor burns and smoke inhalation. The fire service said it believed the blaze started in a bedroom. It has now urged smokers to ensure their cigarettes are fully extinguished and never to smoke while in bed. Firefighters managed to stop the blaze from spreading to neighbouring houses.
