Five people were arrested following a series of UK Border Agency raids in the North East.
The enforcement operations were part of a nationwide summer campaign to tackle illegal working, sham marriages, bogus colleges and organised immigration crime.
Acting on intelligence, officers visited the Hong Kong Chop Suey, in Berwick-upon-Tweed on Tuesday 27 July, questioning staff to ensure they had the right to work in the UK.
Two male Chinese nationals were arrested for immigration offences and taken to Bedlington police station for further interview.
In a previous operation at (G2 Meats) Manufacturing Co in Washington, Tyne and Wear, on Wednesday 21 July, a male Turkish national was found working illegally.
Both businesses were issued with a warning that they could now be fined up to £10,000 for each illegal employee unless bosses can prove they carried out the correct right-to-work checks on their employees.
In a separate operation also on 21 July, enforcement officers visited residential addresses in Gateshead and Sunderland and one Chinese male and a Chinese female were arrested for immigration offences and taken to Gilbridge police station for further interview.
Damian Green, the Immigration Minister, said:
‘The government has tasked the UK Border Agency with carrying out an intense period of enforcement activity over the summer. We are determined to create a hostile environment which makes it harder than ever for illegal immigrants to come to the UK and put down roots.
‘Illegal immigration puts untold pressure on public services at a time when this country cannot afford to support people not entitled to it. That’s why the UK Border Agency is working day in, day out to cut out the routes such as sham marriages, bogus colleges and organised traffickers being used by foreign nationals to try and stay in the UK permanently.’
