In 2010 Gambian police seized 2.34 tonnes of cocaine – worth an estimated one billion dollars – bound for Europe and arrested a dozen suspected traffickers after a joint investigation with British detectives.
Twelve people of various nationalities were also arrested after investigators discovered the drugs in an underground bunker in a warehouse outside the Gambian capital Banjul.West Africa is a major stop-off point for drugs, often from South America heading to Europe, although officials say it is impossible to say exactly where this consignment was heading at this stage.
