Two men were arrested for immigration offences after police carried out modern slavery checks at nail bars in Whittlesey.
These checks involve officers engaging with the workers to ensure that they are safe and there are no concerns around exploitation.
It led to two men, one in their 30s and another in his 20s, being arrested for immigration offences.
Both are currently in custody.
