The importance of work permits in the UK has been highlighted by the arrest of three illegal workers in Rugby.
A raid conducted by the UK Border Agency (UKBA) discovered three people working at Pizza Delicious who did not have the UK work permits required to conduct paid employment.
Two of those arrested were from India and the third was from Pakistan.
While the men are awaiting deportation from the UK, the employer is facing a fine of up to £10,000 for each person employed without the correct UK work permit documentation.
The business has already been given an on-the-spot penalty notice, but if it cannot prove that it carried out the correct right-to-work checks on staff it could face the additional charges in the form of a Civil Penalty Notice.
Alison Spowage, assistant director for the UKBA in Warwickshire, commented: "We are happy to work with employers to help them stay within the rules.
"But any business that takes on a foreign national without permission to work should be aware that it is breaking the law as well as undermining law-abiding employers."
She added that "rogue bosses" should be aware of the fines and possible jail sentences involved in the employment of illegal workers.
