A British diver who helped rescue schoolboys from caves in Thailand has said it was “unbelievable” to find the boys alive.

Rick Stanton, from Coventry, told reporters after arriving at Heathrow Airport in London: “As they were coming down the slope we were counting them so we got to 13. Unbelievable.”

Asked about his emotions when the boys were found, he replied: “Initially, of course, excitement. Relief that they were still alive.

“They looked in good health, but, of course, when we departed all we could think of was how we were going to get them out, so it was relief tempered with uncertainty,” he added.
