A Panorama investigation uncovers how organised gangs are exploiting the UK's private rental market.

A BBC Panorama investigation has uncovered how organised crime gangs are exploiting the UK's private rental market - targeting properties to take over and use for their operations. Among those featured in a new documentary is landlord and property developer Craig Shepheard, who discovered his flat was being used by a prostitution ring, run by a network in Brazil. BBC Panorama reporter Hazel Martin also found that criminals are using fake IDs to get rental agreements.
