Four would-be illegal immigrants have been stopped from entering the UK after Border Force officers found them hiding inside a lorry which was bound for Lincoln.
Two men and two women, all from Vietnam, were discovered at the Port of Calais on September 20, as the Bulgarian registered lorry waited to board a ferry to the UK.
A sniffer dog detected the group hiding among the load of potatoes which were due to be delivered to Mere Road, Lincoln.
The stowaways were handed over to the French border police and the vehicle was allowed to continue onto its destination.
Paul Morgan, of Border Force, said: "This incident shows why we base Border Force staff in France - to stop would-be illegal immigrants before they can reach the UK. "Our strong presence in French ports like Calais helps protect the whole of the UK from people attempting to enter the country illegally."
As well as using sniffer dogs, Border Force officers use carbon dioxide probes, heartbeat detectors, and physical searches to find people hiding in vehicles.
A leaflet, issued by Border Force, in partnership with the Serious Organised Crime Agency (SOCA), gives information and advice to lorry drivers transporting freight to and from the UK on how to prevent illegal immigration and avoid becoming victims of crime:http://www.ukba.homeoffice.gov.uk/sitecontent/newsarticles/2011/july/22lorry-crime-prevent
