A TEMPORARY lock keeper helped rescue a teenage boy who got trapped underwater while canoeing with his father.
Sebastian Cook was manning Radcot Lock near Faringdon on May 29 when the boy ventured too close to a weir and got caught in a small whirlpool.
When the eddy tipped his canoe over, he became trapped underwater.
Mr Cook heard the boy’s father shouting for help and rushed to the scene with a bystander.
They threw the struggling pair a life ring as the father got in the water and hauled his son, now unconscious and blue in the face, out of the water.
The bystander, who turned out to be a doctor, made sure the boy was breathing before an ambulance took him to hospital
