Keith Abrahams, 40, of Hereford, has been arrested in Spain on suspicion of smuggling £5million of heroin into the UK.Spanish Police have broken up a group of Foreign Exchange Agencies who are said to have laundered funds worth around 180 million euros during the last four years.The group appeared to be offering their services to tourists but were in fact dealing with British customers linked to drug trafficking between 2005 and 2009.The Operation began five months ago when officials detected a group of exchange agencies, primarily in Fuengirola, accounting for a disproportionate amount of transfers from pounds to euros despite a lack of British tourists in the area at that time.Investigators have claimed that the agencies played an important role for networks who needed to convert currencies in order to fulfill drug payments.
