An ambulance service has launched an inquiry after a teenager died from an asthma attack after an ambulance allegedly went to the wrong address.
Elouise Keeling, 14, collapsed with breathing problems during an Air Cadets sports day at RAF Brampton near Huntingdon, Cambridgeshire, on June 25.
An ambulance was called at 7.44pm but Miss Keeling's family has told the Cambridge News it was sent to RAF Wyton, seven miles away, by mistake and did not arrive until 8.03pm.
Crews are supposed to respond to the highest priority cases within eight minutes but this journey took 19.
Her family have now called for an investigation into the delays.
A spokesman for the East of England Ambulance Service Trust said it was aware of the complaint but said it was a "complex" matter.
The trust would not comment on whether the ambulance went to an incorrect address.
He added: "We were called on June 25 to reports of an unconscious 14-year-old who had suffered an asthma attack at RAF Brampton.
"A rapid response vehicle, a land ambulance and an air ambulance attended but sadly the girl was pronounced deceased at the scene.
"The incident is currently undergoing a full internal investigation. The patient's family are aware of this and are being kept fully informed throughout the process."
