Two divers are missing after they were reported to be trapped on a wreck off the coast of Cornwall.
The two divers were exploring HMS Scylla, a popular diving destination near Whitsand Bay, when their dive boat reported to HM Coastguard that they had become trapped.
A third diver managed to get to the surface and is being treated for decompression at DDRC in Plymouth.
The coastguard launched a coordinated search with a helicopter from Newquay as well as both Plymouth RNLI lifeboats and Looe’s RNLI lifeboat.
Devon and Cornwall Police are also involved.
The coastguard said the search continued until the early hours of the morning but the divers were not found.
Professional dive units are being brought to assist.
James Instance for HM Coastguard said: “Our thoughts at this difficult time are very much with the family and friends of the two missing divers.”
