In December 2016, nearly 100 people were arrested in nail bars on suspicion of working illegally and breaching immigration laws. Authorities raided 280 nail bars nationally as part of Operation Magnify, a government operation targeting “risk” industries. The majority of those arrested were Vietnamese nationals. Written warnings were also delivered to 68 businesses threatening to fine the employers £20,000 per illegal worker if they had failed to carry out appropriate right-to-work document checks.
