A murder inquiry has been launched following the death of a five-year-old boy four months after a house fire.
The boy, who was taken to Birmingham children’s hospital with substantial burns after the fire last November in Rugby, Warwickshire, died on Thursday morning, police said.
A man, 21, and a woman, 28, both from Rugby, were arrested in January on suspicion of arson. They are on police bail until April.
Two other children, aged eight and 10, and a woman, believed to be their mother, also suffered serious burns in the incident and were treated in hospital.
DI Teresa McKenna, from the major investigation unit, said: “We’re sad to report that the boy injured in the fire has died and as a result this has now become a murder investigation.
“We remain committed to establishing the exact circumstances leading up to the fire and continue to appeal to the public for any information that could help with our investigation.”
