A city Indian restaurant ordered to make “major improvements” following an environmental health inspection has now fallen foul of immigration laws.

Enforcement officers swooped on Jalsha in Wincheap and arrested a 24-year-old Bangladeshi man, who is expected to be deported for breaching his visa conditions.

Two other men – an 18-year-old Eritrean and a 28-year-old Bangladeshi – who had no permission to work were escorted from the site and told to report to the Home Office.

Home Office spokesman Bev Morgan says the business was also served with a notice warning that a fine of up to £20,000 per illegal worker would be imposed unless the employer could demonstrate that right-to-work document checks were carried out.

The raid came just weeks after Jalsha was revealed to be among 10 restaurants and takeaways in the district that had been awarded just one star by the Foods Standards Agency.

The business was told it needed to make major improvements to meet an acceptable standard.

A family member, who did not want to be named, says significant investment has been made in new kitchen equipment, which he believed would result in the restaurant being awarded four stars on re-inspection.

He added the owner was working with a specialist company to ensure illegal workers were not employed.

On its website, restaurant owners the Uddin family say the business “has won many awards”.
