Four men were arrested at an Asian snack food supplier after a UK Border Agency raid.

The raid, on Wednesday last week, took place at Best Food Manufacturers, in Freshwater Road, Chadwell Heath.

Three of the Indian staff members, aged 22, 40 and 50, had over-stayed their visas while another, aged 21, was found to have entered the country illegally.

The 40- and 50-year-olds are currently in immigration detention while steps are taken to remove them from the country at the earliest opportunity.

The other two have been granted immigration bail and will have to report regularly to the UK Border Agency while it looks into their cases.

Best Food Manufacturers were served with a notice which warned that the company will receive a fine of up to �10,000 per illegal worker unless proof is provided that the correct right-to-work checks were carried out.

Steve Fisher, from the UK Border Agency, said: “We regularly carry out operations like this in London, and where we find people who are in the UK illegally we will seek to remove them.

“Illegal working has a serious impact on communities, undermining legitimate businesses and taking jobs from those who are genuinely allowed to work.”
