"Police were called just after 14:20 pm today to reports of concerns for ten people traveling westbound in a lorry on the A14. Officers stopped the vehicle at the Shell garage in Godmanchester", the police said.
The truck’s passengers were taken to hospital, yet no one is believed to have serious injuries, according to the statement.
"Two people have been arrested - one on suspicion of assisting unlawful immigration and the other for suspected firearms offences", the police added, noting that immigration services had been informed.
The media have reported that a pregnant woman and two children were among those illegally transported in the truck.
In October, the UK was shocked by the deaths of 39 Vietnamese migrants frozen in a refrigerator truck in an industrial park in Grays, Essex. Several people have been detained in connection with the deaths, including the truck driver, Maurice Robinson, a man from Northern Ireland, who faces multiple charges, including 39 counts of manslaughter and human trafficking.
