Campaigners in Exeter marked Modern Slavery Day by highlighting the issue with an information stand in Central Library.
Lord Mayor Percy Prowse was among those to visit the Exeter-Anti Slavery Group, who returned to the new-look library on Saturday, having used other locations including the Civic Centre and the Co-op store in Sidwell Street in their quest to raise awareness of the problem in recent years.
Three new members joined the group on the day.
Graham Martin, chairman of the Exeter Anti-Slavery Group, said: "It was great to be back at the library, and although the numbers were small the calibre of people we saw and the after-effect of gaining more members has been greater than elsewhere."
The group is involved in setting up a South West human trafficking monitoring group, following recent raids in Plymouth and Bodmin.
