Illegal work arrests surge as police target 'unscrupulous' employersIt said immigration enforcement officials had "intensified" their work to "tackle those abusing the UK immigration system and exploiting vulnerable people". Arrests for illegal work have surged this past year as police focus on "unscrupulous" employers who exploit undocumented migrants, the government says. Such businesses had often subjected migrants to "squalid conditions and illegal working hours" as well as below-minimum wages. In one case in Surrey, officers arrested nine people at a caravan park who had been working as delivery drivers. At one one major operation in March, officers arrested 36 people at a building site in Belfast's Titanic Quarter.
