A 15-year-old collapsed after a cardiac arrest on Woolacombe beach. An ambulance and an RAF Chivenor helicopter were sent out to help the teenager at around 4.30pm on Friday. An RAF Chivenor spokesman said lifeguards were already on the scene by the time they got there and had managed to resuscitate the teenager. He was transported to North Devon District Hospital. The spokesman said the teenager had suffered from a similar incident previously. It was not known where he lived.
