A shopkeeper from Featherstone was arrested on suspicion of running a bogus religious charity in one of a series of co-ordinated swoops.
The 40-year-old was taken into custody by immigration officials in a dawn raid on Featherstone Convenience Store, on Featherstone Lane, yesterday.
She was one of seven people arrested during operations across the country.
Adrian Watkins, from the Home Office criminal and financial investigation team, said: “These arrests are part of an ongoing investigation into suspected breaches of UK immigration law.
“The investigation will continue with the evidence we have seized.”
It follows inquiries into two West Yorkshire charities that sponsor Indian nationals to come to the UK. The Sri Guru Nanak Jot Parkash Sikh Society and the Guru Nanak Mission UK charities are suspected of bringing people into the country on the false pretext that they will be employed as religious workers or ministers of religion.
As well as Featherstone Convenience Store, officers also visited Birkenshaw Convenience Store, on Old Lane, Birkenshaw, where they arrested two men aged 45 and 24.
The addresses are the respective premises of the registered charities.
Three men and a woman were also arrested in Bradford, Derby and Wolverhampton. All seven of the suspects were arrested on suspicion of conspiracy to facilitate the commission of a breach of UK immigration law by a non-EU national, contrary to section 25 of the Immigration Act 1971.
All the premises visited were being searched for most of yesterday and those arrested are being questioned at police stations across the UK.
