Immigration officers have arrested seven people for working illegally after raids on Dundee restaurants.
The Home Office enforcement team were accompanied by police officers as they checked on the immigration status of employees.
The first arrests came at the New Dragons Pearl, Constitution Street, and involved two Chinese men aged 20 and 42 and a 36-year-old Chinese woman.
Two Indian men aged 30 and 53 working at Halal Indian and Pizza Buffet, Whitehall Street, were the next to be taken into custody.
A 27-year-old Pakistani man was then discovered to be working illegally at Curry in a Hurry in Happyhillock Shopping Centre and later another Pakistani man aged 25 was arrested at Ravvi Tandoori, Cleghorn Street.
All seven have been detained while steps are taken to remove them from the country.
The businesses which employed them will all be served with civil penalty notices for employing the illegal workers.
If the employers are unable to provide evidence that legally required pre-employment checks were conducted for the workers, they will liable for a fine of up to £10,000 per person.
The raids, which happened on Thursday evening, were part of a coordinated campaign that saw a further 14 arrests made at premises in Glasgow along with 17 in Oban and 10 in Wick.
Scotland enforcement team assistant director Adam Scarcliffe said: “The message for anyone living and working in Scotland illegally is clear it doesn’t matter where you are, we will track you down and remove you from the country.
“We’re undertaking operations like this throughout the country on a regular basis, and more are planned.
“We’re happy to work with businesses to let them know what checks need to be made on staff, but those who break the law should know that they will face heavy fines.
“I would urge members of the public with detailed information about suspected immigration abuse to get in touch.”

The Home Office immigration law enforcement organisation has replaced the UK Border Agency, which was previously responsible for seeking out illegal workers.
