A woman has been arrested on suspicion of using multiple disguises to fraudulently pose as 12 other people to help them pass a UK immigration test.
Chris Foster, criminal and financial investigation lead for London, accused the woman of using "wigs and disguises" to "impersonate others and cheat the immigration system, showing a complete disregard for UK safety and immigration laws".
The Home Office said fraudsters completing the test for others could result in people being wrongly granted the right to remain in the country without proper due diligence, "potentially putting the public at risk".
Last week, a woman was arrested on suspicion of fraudulently completing the test for at least 14 people.
Fraud suspect, 61, 'used wigs and disguises' to take citizenship tests for others, Home Office says.
