A major operation took place in Sussex on Monday to find victims of modern slavery and the criminals who exploit them.
It is thought across the country, thousands of people are working in appalling conditions, often for less than the minimum wage, or for nothing.
Officers targeted vans taking people to work on building sites during roadside checks along the A21, south of Robertsbridge.
The operation followed weeks of intelligence gathering.
Modern slavery can take many forms and involve many different industries.
It is a highly-organised crime which forces vulnerable people to live and work in appalling conditions.
Multiple agencies were involved in Monday's crackdown, including members of King's Church Hastings and Bexhill.
