Three men suspected of working illegally in the UK are waiting to be deported after being found at a cash-and-carry business in Birkenhead.
The UK Border Agency raided Spice Net in Westbourne Road, Prenton, on Wednesday and held three Bangladeshi men in their late 30s and early 40s.
It was issued with a civil penalty notice for employing illegal workers.
If the business cannot prove it carried out the right checks, it will be fined £10,000 per worker.
Eddy Montgomery, Operations Director of the UK Border Agency in the North West, said: "This is the latest in a series of operations we've carried out to tackle immigration crime in Merseyside, and more are planned.
"Illegal working has a serious impact on communities, taking jobs from those who are genuinely allowed to work."
He added: "Businesses which operate outside the law should be warned that they will be found and they will be punished."
