Ronald O'Dea, 42, and James McDonald, 39, both from Glasgow, were detained following police raids in November. Londoners Stephen Denis Brown, 42 and Brian Rawlings, 63, were also arrested in a joint operation with the Scottish Crime and Drug Enforcement Agency. The men are expected to spend several months in prison before facing trial at the National Criminal Court in Madrid. The operation also resulted in the arrest of Gerard Mooney, from Dublin, in October 2008. It is alleged that a truck that he was driving to Scotland contained 70kg of speed when it was stopped by police near Oxford. The subsequent raids in Marbella, on the Costa del Sol, and Tenerife, in the Canary Islands, resulted in the Britons being arrested. The money laundering charges relate to the seizure of property in Spain along with luxury goods worth nearly £11m. These included a Ferrari F430 Spyder, a 599 Fiorano, two Hummers, a Porsche Cayenne turbo, an Audi Q7, a Mercedes 63 AMG and two BMWs. A luxury yacht was also confiscated.
