Immigration squads swooped on a Blackpool takeaway after a tip off about visa breaches.
Border police visited the Chutney Blue takeaway on Marton Drive, Blackpool, and spoke to four occupants, including the owners.
A 27-year-old Bangladeshi man was arrested for over-staying his visa, after a team of five officers, with reinforcements on standby, entered the premises at 6pm on Wednesday.
Three other people at the property, comprising a takeaway and upstairs flat, were spoken to by officers, including the owners, a husband and wife with British passports.
A second Bangladeshi man was found to be in the country on a valid student visa.
Home Office Immigation officer Chris Eccleshall, leading the investigation, said: “This was a standard immigration visit to see if anyone was working illegaly.
“We spoke to the staff and one Bangladeshi man was arrested for being an overstayer in the UK.”
Neighbours told of their shock to see the officials arrive at the eatery, which serves Indian food as well as kebabs and burgers.
One woman, who asked not to be named, said: “I’m not sure how many people live there but a lot come and go, you don’t want to poke your nose in though.
“I was shocked to see immigration turn up but not really suprised by it.”
It comes almost three months after a Bangladeshi man was arrested and later deported after being found to be working illegally at the Red Fort restaurant on Park Street, Lytham. The incidents are not connected.
