Beds Police state that 14 people found in the back of a refrigerated lorry at Toddington services this morning have been detained.
The driver has also been arrested on suspicion of facilitating illegal entry into the UK and officers are trying to establish if the driver had any involvement.
The detainees have been split across Luton and Kempston custody and await Immigration Enforcement.
Police stated that Bedfordshire’s infrastructure and transport links make the area, especially Toddington motorway services, a prime location for call-outs involving immigration offences.
PC Ken Foster said: “Jobs like this are hugely resource intensive. The coordination of the job was one of the biggest challenges. The language barriers, confusion and desperation. The need to keep families together.”
Last year 563 people were arrested or detained in Bedfordshire on suspicion of immigration offences. In the first three months of 2016 there has been 80 arrested or detained.
