Three illegal immigrants were found working at a High Street takeaway in Montrose.
The Yummy Chinese takeaway was raided by immigration enforcement officers in an intelligence-led operation.
Three Chinese men, aged 37, 41 and 54, were found to have entered the country illegally and were arrested. Steps are being taken to remove them from the UK.
Yummy was served a referral notice in relation to the three workers, warning that a financial penalty of up to £20,000 per illegal worker will be imposed unless the employer can demonstrate that appropriate right-to-work document checks were carried out.
These include seeing a passport or Home Office document confirming permission to work.
Assistant director Ian Tyldesley, head of the Scotland immigration enforcement team, said: “I urge anyone with specific and detailed information about suspected immigration abuse to get in touch.”
