A woman and a nine-year-old boy are seriously ill in hospital after being rescued from the sea.
Police said they were called after a report of the pair being taken from the water at Woolacombe Beach in north Devon amid "heavy" surf conditions in the region.
Both were unconscious when they were rescued by lifeguards from the Royal National Lifeboat Institution (RNLI).
The woman, who is in her late forties, and the boy were flown by RAF helicopter to North Devon Hospital.
They are "seriously ill", Devon and Cornwall Police said.
A statement from the force added: "The police are on scene and obtaining key witness accounts. The incident is not being treated as suspicious.
"The surf conditions were heavy today and the RNLI have dealt with a number of incidents in the north Devon area."
A spokeswoman for the Maritime and Coastguard Agency said: "The Chivenor search and rescue helicopter, the Mortehoe Coastguard Rescue Team and Woolacombe Lifeguard, together with Devon and Cornwall Police, responded to a call, received by Swansea Maritime Rescue Coordination Centre at 1445, that a person had got into difficulties and had been pulled from the water at Woolacombe.
"It transpired that two people - a woman and a child - had been pulled from the water and were in need of immediate medical assistance.
"They were airlifted to North Devon District Hospital."
