Six men and four boys suspected of entering the UK illegally have been treated for the effects of cold after they were found in the back of a refrigerated lorry.
Ambulance crews were called near a retail park off the M6 after the group were discovered in Wednesbury, West Midlands, at 5.31pm on Thursday.
The HGV was reportedly stopped by motorway police as it travelled north after other motorists spotted arms hanging out of the vehicle, apparently gesturing for help.
Police contacted Immigration Enforcement at around 6pm and they are now processing the 10 males, who said they were from Iraq, Iran, Vietnam and Lebanon.
A spokesman for West Midlands ambulance service said medics had assessed and treated the males for the effects of cold.
Staff at a branch of Costa Coffee at the retail park served them hot drinks, while one was taken to Walsall Manor hospital after he fainted. All are thought to be aged between 16 and 26.
The Home Office said that six of the males would be referred to Immigration Enforcement to be interviewed, while four, who said they were minors, would be passed into the care of social services to be age-assessed.
Two Spanish men, aged 50 and 60, were arrested by West Midlands police on suspicion of facilitating illegal immigration and the case is now being led by Immigration Enforcement criminal investigations.
Immigration Enforcement, part of the Home Office, is responsible for enforcing immigration law. A Home Office spokesperson said: “Where someone has no right to remain in the UK, we will take action to remove them.”
