A three-year-old who died for six minutes after suffering a cardiac arrest has thanked medics who brought him back to life.
Kai Clark suffered the attack at his home in Clacton-on-Sea, Essex, on October 17. He stopped breathing and his heart stopped beating.
His mother Kelly Clark was with him at the time and she said she feared for the worst until paramedics and the air ambulance arrived.
Without the expertise and team-work between the medical crews and the rapid transfer to a specialist hospital, doctors said Kai would almost certainly not have survived.
Mrs Clark said: "I was trying to resuscitate him myself but I feared it was too late. "It was the most frightening experience you can go through as a parent. "They arrived so quickly and it was an enormous relief.
"He still has some medical complications and it has been a hard process to get to this point, but to see him walking and smiling again is amazing."
The family visited Cambridge Airport, where the East Anglian Air Ambulance is based, in order to thank the helicopter crews and the East of England Ambulance Trust.
