UKBA officials in Dunquerque found six men in a lorry full of shopping trolleys 04 November 2008. Four Indians and two Afghans were discovered hiding in the back of a lorry, amongst shopping trolleys, reported the UK Border Agency.
The officials searched the Polish-registered lorry on Wednesday October 29 before it was due to board a ferry to Dover.
The men were handed over to the French authorities. A UK Border Agency spokesman said: "The UK Border Agency has hundreds of British immigration officers based at ports in France and Belgium, working to stop illegal immigrants before they get to the UK."
"As well as visual checks of vehicles, officers also use heartbeat detectors, carbon dioxide machines and sniffer dogs to find well-hidden stowaways."
