Following the story of Reynard Sinaga - "the most prolific rapist in British legal history" - 5 Live hears from survivors of male rape and the man who led the prosecution. Sinaga was found guilty of 159 sex offences, including 136 rapes, and sentenced to life in prison. The 36-year-old targeted men leaving nightclubs and bars before leading them to his flat in Manchester city centre, where he drugged and assaulted them - filming the attacks. 5 Live's Nicky Campbell speaks to deputy chief crown prosecutor Ian Rushton, who led the team in the Reynhard Sinaga case, and male rape survivors such as James, who was also targeted by a man on a night out.
