The tourist is in 21 hours sunburned at sea (Photo)

A Russian tourist was found at sea in 21 hours with only a swollen water mattress.

Olga Kuldo has been rescued from the control group that was searching for illegal immigrants on the coast of Crete.

The 55-year-old from Russia collapsed at the Rethymno resort in the Greek island north, after being swept into a strong current.
She stayed all night at sea and was badly burned by the hot sun the next day.

Dramatic images show how it swims in despair as Frontex workers throw a rope to get it up their ship.

She has been sent to the hospital for medical treatment for exposure to the sun and heart problems after staying long in the water.
