Twenty-one people were found hidden in the back of a refrigerated lorry carrying a cargo of sparkling water on Thursday (November 1).
Border Force officers intercepted a lorry at Newhaven Port which arrived on a ferry from Dieppe, France.
The group, thought to be from Vietnam, contained 17 people who claimed to be aged between 12 and 17-years-old.
A total of 11 were later confirmed to be minors and were passed into the care of social services, according to the Home Office.
The remaining adults, five women and five men were interviewed by immigration officials.
Two of them, an 18-year-old man and a woman aged 27, have since been removed from the UK the Home Office said.
The remaining eight, all aged between 21 and 28, must now report regularly to the Home Office while their cases are progressed in line with the UK immigration rules.
A spokesperson from the Home Office said:
“On Friday, November 2, 29-year-old Andrut Mihai Duma, a Romanian national of no fixed UK address was charged with assisting unlawful entry to the UK.
“He was remanded in custody to appear at Lewes Crown Court on November 26.”
