A British couple in their 70's have been detained after a "large amount of cocaine" was found in their cabin on a cruise ship returning from the Caribbean.
The pair, aged 70 and 72, were arrested on December 4 when the Marco Polo ship, operated by Cruise and Maritime Voyages, docked in Lisbon and their cabin was searched.
Police found almost 10kg of the class A drug hidden in four suitcases.
The Policia Judiciaria in Portugal said the pair were detained in Lisbon after they received information from the UK National Crime Agency.

The pair were arrested on suspicion of trafficking narcotics and have been remanded in custody.
The pensioners have appeared before a judge and are being held in custody while a joint Portuguese and British investigation continues.
After the elderly couple were arrested, the ship continued on its planned route and returned to the UK on December 8.
Cruise firm 'does not tolerate any criminal activity'
A spokesperson for the cruise liner said the company did not tolerate "any criminal activity or anti-social behaviour on board".
"Portuguese police officials attended the Marco Polo in Lisbon on December 4 and detained two passengers who were travelling on board the Cruise and Maritime Voyages vessel," the spokeperson said.
"It is understood this was in connection with the suspected possession of narcotics. Cruise and Maritime Voyages is co-operating fully with the Portuguese police officials."
