Two people have been arrested after immigration officers visited a nail bar.
Shenley Nail Bar, in Shenley Road, were visited by immigration enforcement officers at around 10am today to check that employees had the right to live and work in the UK.
Officers arrested a 39-year-old Vietnamese man who had overstayed his visa, along with a 28-year-old Vietnamese woman who had previously been arrested as an illegal entrant to the UK.
Both were placed on immigration bail and will have to report regularly to the Home Office while their cases are investigated.
The nail bar has now been served a civil penalty notice and will be fined up to £20,000 for each illegal worker if they cannot provide proof that the correct right to work checks were carried out.
Lionel Garriock, assistant director of east of England immigration enforcement, said: "This is a warning to businesses either deliberately employing people with no right to work or failing to carry out the legally required checks on their staff. We will catch up with you and you should expect to face heavy financial penalties.
"We rely on intelligence from members of the public, and I would urge people with information about suspected immigration abuse to get in touch.”
