Police have found a 10-year-old boy with a rare medical condition who went missing today, prompting fears he may have fallen into a coma.

Scotland Yard issued an urgent appeal to trace Malakhi Chijiutomi-Ghosh, who suffers from adrenal hyperplasia and requires medication three times a day.

He left his home in Thornton Heath, south London, at 6am and was last seen at a bus stop in nearby Streatham Common around two hours later.

A police spokesman said the youngster had been found by an off-duty police officer in Hertfordshire and taken to hospital as a precautionary measure.
