Police were out in force on Wednesday after a lorry containing 15 illegal immigrants from the Middle East was stopped in Dunstable.
It is understood the drama took place in Church Street, Dunstable, with a large number of police cars present.
A Beds Police spokesman said: “Fifteen suspected illegal immigrants were arrested in Dunstable yesterday, April 29. Officers responded to reports of people seen in the back of a lorry at about 4.30pm.
“The driver of the lorry has been arrested on suspicion of facilitating entry. All remain in custody and enquiries are on-going.”
Ambulance were also in attendance after many of the men were noted to be suffering from breathing difficulties.
Five were taken to Luton and Dunstable hospital, but their condition is not thought to have been life-threatenening.
A Home Office spokesman added: “Home Office Immigration Enforcement was contacted by Bedfordshire Police yesterday, April 29, after police attended an incident in Dunstable.
“Fifteen males, made up of seven Syrians, five Iranians and three Iraqis, were arrested on suspicion of immigration offences and remain in police custody pending their transfer to Home Office Immigration Enforcement.”
