Police are concerned for a missing 12-year-old diabetic boy who has not had insulin for 24 hours.
Alfie Cummings, from Birchington, is a type 1 diabetic and depends on his medication.
He was last seen on Monday when he had his last jab, and has now missed two shots. Officers said he knows that he needs to take his medicine.
Kent Police have released this photograph of the child in an appeal for help in tracing him.
A spokesman said: "He has disappeared before for short periods of time, but never for this long.
"He is aware of his condition and the need to take his medication regularly."
The schoolboy is described as 5ft 2in tall, with short blond hair, and a mole between his lip and his nose.
He was last seen wearing a grey and blue hooded top with a diamond motif on the back, black Adidas tracksuit bottoms, a black puffer-style jacket, and black training shoes.
