Six illegal workers have been caught by the UK Border Agency at two businesses in Lincolnshire.
On December 20, officers, supported by Lincolnshire Police, paid an unannounced visit to The Bengal Clipper in Broad Street, Stamford.
Checks were carried out on the immigration status of all staff.
Two Bangladeshi men were arrested after neither was found to have the right to remain in the UK.
On January 10, officers visited China Palace Restaurant in South Street, Bourne, where they arrested four Chinese nationals – three men and a woman – who did not have permission to work in the UK.
All six illegal migrants remain in UK Border Agency detention while action is taken to remove them from the UK as soon as possible.
Both businesses were served with potential fines of up to £10,000 per illegal worker which will have to be paid unless they can prove they took legally required steps to confirm the right to work of the foreign nationals, such as checking passports.
Paul Tranter, from the UK Border Agency in Lincolnshire, said: “Any foreign national who is in the UK illegally should be in no doubt that they will be found, arrested and removed from the country.
“Businesses that take on illegal workers face heavy fines and possible prosecution.
“We urge any members of the public to please report any suspicions about people who might be here illegally.”
