Ten quizzed over money laundering Ten people have been arrested in Spain and the UK in connection with a money laundering scheme thought to have processed up to £80m a year. Seven Britons were arrested in Marbella and Madrid, with a further three detained in Birmingham, Slough and Tamworth on Tuesday and Thursday.
It follows a nine-month joint investigation by Spanish and British police as well as customs officials.
The network is thought to have global links to other launderers.
Detective Chief Inspector Tim Tyler, of the National Crime Squad, said the group were believed to have used businesses - including an airline and a clothing manufacturer - to conceal bulk movements of cash.
A Spanish national has also been arrested.
An application is being made by the Crown Prosecution Service to have certain assets restrained in the UK following the arrests.
