Twenty-one people, including children as young as 12, have been found inside a refrigerated lorry entering the UK.
The group, thought to be from Vietnam, was concealed among a load of sparkling water at the port of Newhaven in Sussex on Thursday, bbc.co.uk informs.
Details of the Border Force operation have only just emerged, but a criminal investigation is under way.
A Romanian man, believed to be the driver, has been charged with assisting unlawful entry into the UK.
It had earlier been reported 15 children had been found in the lorry, but the figure was later revised by the Home Office. A spokesman said the group included 17 people claiming to be aged between 12 and 17 who “presented themselves as Vietnamese”.
