An anti-nuclear campaigner who swam into a submarine base has been rescued from the Firth of Clyde.
Coulport and Faslane are part of Her Majesty's Naval Base Clyde
RAF rescuers pulled the man from the water around Coulport naval base just before 0230 BST after a protester raised the alarm.
The Ministry of Defence said the man was taken to hospital and treated for shock before being arrested by police.
Coulport is part of Her Majesty's Naval Base Clyde, home of the UK's Trident nuclear submarine force.
The rescued man was one of four activists who tried to swim into the base. Three were stopped before they got inside the outer boundary.
A spokesman for the MoD said: "A group of swimmers were spotted and subsequently removed from the water outside Coulport naval base by police launch.
"In a separate incident a concerned protester phoned into Coulport inquiring as to the whereabouts of another protester who was also believed to be in the water.
"An RAF search and rescue operation was conducted and he was found, removed from the water and taken to hospital for treatment for possible post-immersion shock.
"This individual is now in the custody of police."
