A woman has been rescued by a helicopter from RNAS Culdrose after tombstoning off cliffs near Praa Sands in Cornwall.
Coastguards and paramedics attended the scene
The 26-year-old jumped into the sea but suffered severe abdominal pain while getting out of the water and collapsed trying to get back up the cliff.
Just after 1400 GMT a rescue helicopter was on the scene at Bessy's cove.
Falmouth coastguard Roger Mason said: "Tombstoning is dangerous because you just don't know what's underneath you."
The woman was winched up to the helicopter on a stretcher.
Mr Mason added: "If someone is jumping off a cliff then the generic term is called tombstoning.
"It's just as dangerous when it's 6ft high or 20ft high."
A Coastguard team from Porthleven and Ambulance Paramedics were also on the scene.
The woman was taken to the Royal Cornwall Hospital at Treliske by members of 771 squadron.
She is said to be in a comfortable condition in hospital.
