Reports of "banging and shouting" resulted in the discovery of three people in the back of a lorry in Huntingdonshire.
Cambridgeshire Police officers were called to Molesworth on November 14 after they received reports of loud noises coming from the back of a lorry.
The force discovered three men in the back of a trailer who had been inside there for three days.
The men were checked over by the ambulance service and the three were given the all clear medically.
Two of the men have since been arrested for immigration offences, while a third, a teenager, was taken into police protection.
