A modern slavery poster campaign has been launched alerting people to the signs of exploitation to look out for.
Crimestoppers wants to encourage reporting across Lincolnshire and provides an avenue for anonymous reporting of concerns for those who prefer not to give their details.
It says this may be for many reasons, including people not sure their concern is valid or they may be fearful. Intelligence is shared with the police and other law enforcement agencies to develop.
The posters also provide other reporting avenues including the Gangmasters and Labour Abuse Authority and the Modern Slavery Helpline.
