The arrest was made during a series of raids targeting suspected immigration violations in Exeter.
Shocked diners had their evening interrupted on Tuesday when officers from the UK Border Agency made two arrests at Real India in South Street, Exeter.
Agency officers also visited Red Rose Indian restaurant in North Street and checked the immigration status of staff.
Another suspect was later arrested at the Red Rose.
