The BBC reported on the immigration raids that occurred recently.
Seven people have been arrested in raids by UK Border Agency officers on restaurants and takeaways in County Durham and Tyneside. In one Indian restaurant in Durham three Bangladeshi men were found working illegally while in a Chinese takeaway two more people were arrested.
Three further arrests were made in another Indian restaurant and a fish and chip shop in Wallsend.
An agency spokesman said the raids followed tip-offs from the public.
