Online pimps: Police raid suspected brothel
A classified ads website is being used to exploit sex workers and trafficked women, a BBC investigation has found.
Panorama has uncovered evidence that pimps are using Vivastreet to advertise multiple women under their control.
The programme also followed Lancashire police as they raided a suspected brothel.
Vivastreet says it is committed to eradicating any potential exploitation and says providing a safe platform is its top priority.
