The suspect is in custody in Maidstone, Kent, after being handed over to the UK authorities.

A spokesman for the Foreign Office said: "There was an extradition hearing yesterday.

"The Moroccan court agreed to his extradition."

He now faces questioning about the £53 million cash robbery in Tonbridge in February 2006.

Kent Police would make no official comment on the case.

Five other men were convicted on Monday at the Old Bailey in connection with the robbery plot. But police are still hunting several other suspects.

The robbers kidnapped Colin Dixon, the manager of the Securitas depot in Tonbridge, Kent, and his wife and child, before getting away with what prosecutors described as a "king's ransom".

Police recovered £21 million of the cash at sites in Kent and south east London but much of the rest was thought to have been spirited away to Morocco and northern Cyprus.
