Police detained another six suspected illegal immigrants yesterday, this time at a busy service station on the M1.
Bedfordshire police said they had several calls from people who spotted the suspects near Toddington.
Officers arrested all six and took them to Luton Police station.
The service station is one of the first stops for truckers coming from the Port of Dover, after leaving Calais in France.
Local farmer Chris Gadsden, 60, said the problem is so severe he has been catching immigrants on his land and handing them over to the authorities.
This comes on top of several arrests on the M1 and at the services in recent weeks after police received tip offs of men seen leaving lorries
