A 12-YEAR-OLD boy left critically ill following a house fire in Penistone has died as a result of his injuries.
Emergency services were called to a house on Tennyson Close at around 6.30pm last Wednesday.
A man and his two sons were rescued from the property by firefighters but Darren Sykes, 44, and his nine-year-old son Paul both died as a result of the fire.
His older son Jack was taken to hospital in a critical condition but lost his fight for life on Monday night.
Detectives investigating the fire have confirmed it was started deliberately and that an accelerant was used.
