Home Office immigration raids have led to the discovery of 16 illegal workers in South Yorkshire.
The latest five were arrested when officers raided two takeaway businesses in Sheffield and visited a market stall on Wednesday.
Two Chinese men, aged 23 and 47, were arrested at the Golden House takeaway, Richmond Road, Richmond, after checks revealed they had no right to be in the UK.
And two Bangladeshi men, aged 31 and 52, were arrested at Tikka Masala, South Road, Walkley.
A 26-year-old failed asylum seeker from Afghanistan was arrested after attempting to flee from officers when they visited a market stall on Castlegate Market, Sheffield.
The arrests follow three that took place on Tuesday after officers found two illegal immigrants, aged 30 and 40, from Bangladesh, during a visit to the Mint Leaf restaurant on Green Lane, Dronfield.
A 37-year-old Turkish man was also arrested for immigration offences at Zorbas Pizza, High Street, Sheffield.
Last Saturday eight illegal workers from Pakistan, Vietnam and Bangladesh, were discovered at Chicken Cottage, Wicker Road, Sheffield, Asian Spice, Sandringham Road, Doncaster and Hollywood Nails, Market Road, also Doncaster.
All the businesses involved have been served with civil penalty notices for employing illegal workers, meaning bosses will be fined up to £10,000 per illegal worker unless proof is provided that right-to-work checks were carried out.
Assistant director Anita Bailey, from the Yorkshire and Humber Home Office Immigration Enforcement team, said: “These arrests show there is no hiding place for people who are in the UK illegally, and the employers who choose to exploit them.
“We are determined to tackle illegal working in South Yorkshire and our teams carry out intelligence-led operations like this all year round.
“Illegal working is not a victimless crime – it defrauds the taxpayer, undercuts honest employers and cheats legitimate job seekers out of employment opportunities.
“We are happy to work with employers to let them know what checks need to be made, but those who break the law should know that they will face heavy fines.
“I would urge members of the public with detailed and specific information about suspected illegal working to contact us.”
