A four-year-old girl was found asleep on her boogie board a mile and a half out at sea by a passing jet skier.

Jemima Chambers, was playing in shallow water on a family holiday in Jersey, when she began to drift off.

Her mother, Rebecca Chambers, raised an alarm when she noticed her daughter missing and hopped on the back of a man's jet ski to search for her daughter. 

She was found peacefully sleeping on her board in the middle of the sea and was brought back to shore within minutes.

"We spotted this dot off the headland but we couldn’t even make out it was a body but it was her," Jemima's aunt Rachel Le Marquand told the Metro.

"The wind was offshore and she’d floated right around the corner, far too far out to swim. I don’t think the kids really realised quite how serious the situation was," she added.

The Chambers of Gloucester has issued an appeal to find the anonymous jet-ski hero who helped them save Jemima so that they can thank him properly.
