A 34-year-old man has been arrested after an immigration raid in Abergele.
Acting on intelligence, immigration enforcement officers visited Spice Merchant Indian Restaurant, on Chapel Street on Thursday 13 February at 7pm.
Following immigration checks a 34-year-old Bangladeshi man was arrested for overstaying his visa.
The man is in detention pending his removal from the UK.
The businesses was served a notice warning that they face civil penalties of up to £10,000.
The penalty will be imposed unless proof is provided by the employer that the correct right-to-work checks were carried out.
Richard Johnson, from the Wales Home Office Immigration Enforcement team, said: “The message to employers in Wales who choose to use illegal labour is clear. We will catch you and you will face a heavy penalty.
“Illegal working has a negative impact on communities. It defrauds the taxpayer, undercuts honest employers and cheats legitimate job seekers out of employment opportunities.
“I would urge members of the public with information about suspected immigration abuse to contact us directly.”
