This is the moment rescuers fight to save the life of a British sailor who collapsed after being stung by a wasp on his boat in Turkey.

The incident happened off Bozukkale in Marmaris, a resort town in south-western Turkey, on 11th September.

Nick Chapman, 74, lost consciousness after the sting to his knee. The retired engineer and 12-year sailor, from England, later recalled: "I wasp stung my knee and that's the last I remember."

His wife, Claire Chapman, sent a distress call and two Turkish captains responded.

They boarded the yacht with adrenaline from nearby vessels and injected him under the guidance of a cardiologist.

Nick regained consciousness before Coast Guard personnel transferred him to an ambulance at Sercelimani.

He was taken to Mugla Sitki Kocman Training and Research Hospital where he was treated for three days.

Nick said: "I woke up seeing Captains Doga and Caglar and the Coast Guard team.

"Within half an hour, I was on my way to the hospital. If I am alive today, it's thanks to them."

He has since been discharged.
