Four held in Presteigne and Port Talbot immigration checks
Five people have been caught in Powys and Neath Port Talbot following checks by immigration officers.
They visited The Cabin Chinese takeaway in Presteigne last Friday where one man's business visa had expired.
Another man and woman were found to be in the country illegally.
Meanwhile in Port Talbot, a Sri Lankan man was arrested for overstaying his student visa and an Indian man working at a Nisa shop in Victoria Road had no permission to work.
The Chinese takeaway workers and the Sri Lankan man, who was found in neighbouring accommodation owned by the Nisa shop manager were arrested and steps are being taken to remove them from the country.
The shop worker had no permission to work and must report regularly to the Home Office while his case is assessed.
Both premises have been informed they face fines of up to £20,000 unless they can demonstrate that appropriate right-to-work document checks were carried out.
