Nine people, including three children, have been arrested after they tried to flee from the back of a lorry in a Cambridgeshire village.
Witnesses described seeing the group of illegal immigrants walking through Thriplow at lunchtime before seeing police officers and the police helicopter circling the area.
Six adults and three children were arrested yesterday (August 28) and claimed to be from Sudan, Ethiopia and Eritrea.
Scott Manning, who works nearby, said: "Some of the team at work saw up to 10 people walking through the village of Thriplow around lunchtime, and didn't think much of it and then from 1.30pm to 2pm onwards you could hear the helicopters flying low over the office which got a lot of people's attention - the helicopters were searching the area."
He added: "There was no drama or violence from what I could see myself.
"Although I could only see a couple of people they had rounded up, colleagues said a lot more entered the village but from the sounds of it they weren't attempting to hide. The helicopters were searching over the fields going toward the A505."
A spokesperson for the Home Office said: "Immigration Enforcement was contacted by Cambridgeshire Police on Tuesday, 28 August after police officers attended an incident in Middle Street, Thriplow.
"Six adults – four men and two women – were arrested for immigration offences. Of the six, one presented themselves as Sudanese, two as Ethiopian and three as Eritrean. Three minors, who presented themselves as Eritrean, were also arrested for immigration offences.
"The Home Office will progress the cases in accordance with the immigration rules.
"The three minors were referred to social services."Where someone is found to have no right to remain in the UK, we will take action to remove them.
