Cambodia - Exploitation Investigation

In the first episode of a new series of Exposure, former police detective Mark Williams Thomas goes undercover in Cambodia, a country struggling with its reputation as a haven for child offenders. Posing as a British tourist, he meets men who are willing to supply two girls aged nine and ten for $800, or just over £500. One trafficker describes how he brings children as young as 12-years-old to tourists' hotel rooms. Williams Thomas also tracks down a British schoolteacher who was jailed by the Cambodian authorities in 2012 for offences.
