Three people have been arrested in Cornwall as part of a nationwide campaign to tackle the exploitation of trafficking victims.
Officers in Truro arrested two eastern European men in their 20s and a local 60-year-old man on Thursday morning.
They also recovered two potential victims, both women, who are also from eastern Europe.
Operation Pentameter was set up in February specifically to tackle exploitation within the sex industry.
The officer in charge of Thursday's operation, Acting Det Ch Insp Chris Brown, said: "The investigation continues and should serve as a warning to organised gangs within our boundaries that we will not allow such activity to flourish and will strive to identify and recover other potential victims.
"We seek the assistance of our communities to assist us in this operation, and where the public suspects this activity is occurring in their neighbourhoods, we urge them to come forward with the information".
The three men arrested are being held in police stations across the county.
The suspected victims are being interviewed by specially trained police officers and will be offered medical assistance if necessary and then found suitable accommodation.
