UK Border Agency officers are investigating after a lorry driver was stopped while trying to leave the country with £270,000 in cash.
The British man was driving outbound through Dover Eastern Docks in the early hours of Monday, 8 March when his vehicle was searched by UK Border Agency officers.
The cash was found in his cab, while a search of his home address found more cash and a quantity of white powder.
The substance is currently being tested to establish whether it is an illegal drug.
The man was arrested and is currently being questioned further by officers.
Any money seized by the agency is held for three months while investigations are under way. It is then confiscated and returned to the public purse if shown to be associated with criminal activity.
