A body - thought to be that of missing teenager Robert Merton - has been pulled from the sea off St Agnes.
The coastguard and lifeboat recovered the body, which is believed to have been in the water for some time.
There has been no official identification, but police say they may have found the St Martins 17-year-old.
Robert, a well-known gig rower and cricket player, was reported missing after leaving home for a paddle in his canoe on July 26.
His family has been informed of the discovery.
