Those found in the lorry are all men aged between 16 and 30, and their nationalities are not yet known.

Fourteen of them were deemed fit and well and were taken into custody, while the fifteenth was brought to hospital before being arrested.

A police spokesman said: ”We were called by a member of the public shortly before 8.30pm following a report of suspicious activity involving a lorry on the A350 near Chippenham.

”Officers attended the scene and located 15 people in the rear of the vehicle.”

Seán Delaney and Sons in Glanmire in Cork have confirmed this morning to Cork’s 96FM that the lorry was one of theirs.

”We can confirm that the truck involved in last nights incident in Chippenham was one of our ‘Delaney Transport Trucks,” the company said in a statement to The Neil Prendeville Show.

”Our driver was on the way from Callais to Dover. The driver heard knocking and thought it was a flat tyre,” Mr Delaney said.
