Earlier this month, a group of 16 suspected illegal immigrants found in the back of a lorry were detained after one of them called 999 from the back of the vehicle to raise the alarm.
Officers were alerted by one of the 16 men who said he and the others were in the back of a wagon on the A41 in Oxfordshire near the upmarket Bicester Village shopping outlet.
Police arrested the lorry driver and detained the asylum seekers.
