LONDON: Four men were arrested after immigration officers swooped on a builders' merchant in Southall last week.

Officers from the UK Border Agency descended on Western Timber and Builders' Merchant on Western Road last Thursday morning, where they questioned staff to see if they had the right to work in the UK.

Three employees, all Indian nationals, were arrested. A 27-year-old man was arrested for entering the country illegally, while two men aged 34 and 25 were failed asylum seekers.

A fourth man, believed to be a customer, was also arrested for immigration offences.

Three of the four remain in detention awaiting removal from the UK. The 27-year-old was later granted leave to remain while his case is dealt with.

Western Timber and Builders' Merchant must now prove that it had conducted the correct checks on all of its staff.
