Detectives are continuing investigations into the death of a five-year-old boy who suffered severe burns in a horrific car fire.
Tommy Sheldon from Southampton, died in hospital on Monday after being badly burned two weeks ago, despite being rescued from the car by two passers-by.
Officers have not made any arrests but admit that the probe will take a significant amount of time.
Tommy’s mother, 37, and his sister, six, are still in hospital suffering from “serious injuries”.
Officers are now treating the incident as a murder inquiry.
Anyone with information is asked to contact the Hampshire Major Investigation Team, quoting operation Ursula, on 101.
