CAR wash workers are at risk of being victims of modern slavery and exploitation, police say.

In a post on social media, Wiltshire Police urged people to look out for staff being exploited when they visit car washes in the county.

It read: “Those working in hand car washes are known to be at greater risk of being victims of modern slavery and exploitation.

“We need your help to protect those being exploited at these types of businesses.

“By downloading the Safe Car Wash app and answering a few questions about the working conditions the next time you use a hand car wash you could help us collect intelligence and prosecute those exploiting their workers.”
