The three men believed to be victims of slavery were freed following five weeks of investigations by detectives. This morning they raided three travellers sites in South Gloucestershire: Northwood Park, Tall Trees and Green Orchard.
Further raids were mounted at Green Acres Business Park and on two properties in Bristol, one in Kingswood and the other in Redland. The nationality of the men freed is not yet known.
A "significant quantity" of cash was found at one address, while a suspected stolen trailer and cannabis plants were seized from a farm in Yeovil.
Avon and Somerset Police and Crime Commissioner Sue Mountstevens said: "Today's operation clearly highlights the unacceptable and illegal crime of human trafficking.
"It shows that modern slavery is happening around us and I am pleased that the police, local authorities, and the charity Unseen UK have worked together to tackle and disrupt this abhorrent network of criminality.
"It is only by agencies and local communities working together that this crime against humanity will be stamped out. There will be a long road to recovery for the victims and I am reassured that they are getting as much support as possible."
