A submarine which police say may have been used for cocaine smuggling has been found floating off Spain's north-western coast.

It was spotted by a member of the public in an inlet along the rugged coastline on Sunday.
No drugs were found on board the vessel, but it is now being dismantled at a shipyard in Moana, near Vigo.
It is reported to be about 10m (33ft) long, made by amateurs from basic materials, not by professionals.
Jaime Gonzalez, a journalist in the north-western city of Santiago de Compostela, told the BBC World Service's Europe Today programme that the region was well-known as a gateway for drugs into Europe.
While submarines are not known to have been used for drug trafficking in Spain, they have been used for this purpose in Colombia.
"It could take drugs from a ship in the ocean and take them to the coast without being seen," Mr Gonzalez said.
"There has been nothing like this before in Spain. It is an example of how narco-traffickers are advancing in technology."
Mr Gonzalez said it was thought that the submarine could have been built in southern Spain, in Andalucia, and brought to the north-western region of Galicia by road.
He said one theory was that the vessel was undergoing tests when a technical problem arose.
The owners may have been planning to return to it, he added, if the police had not got there first.
