Reynhard Sinaga was described by a prosecutor as “the most prolific rapist in British legal history” and possibly “in the world”, as he was convicted of 159 sex offences. The 36-year-old PhD student was found guilty of attacking 48 men who he would lure from outside of different venues in the city to his apartment. He is said to have taken “a particular pleasure in preying on heterosexual men” if they got in trouble. Some had no money for a taxi home or would have a dead phone battery, and would go back with Sinaga having been offered a floor to sleep on or an invitation to have a few more drinks. This is how he drugged them, and then committed a sexual assault, video recording it, later boasting to friends about what he had done. Police said that there is evidence of Sinaga targeting at least 190 victims. Many woke up without any memory of their ordeal, leading a judge to conjecture that Sinaga had used a date rape drug such as GHB. The rapist was already serving a life sentence with a minimum term of 20 years after being convicted of offences in two earlier trials. A judge has now increased this to a minimum of 30 years and lifted reporting restrictions, allowing him to be named for the first time. The trial focused on crimes committed between January 2015 until his arrest, however it is thought that Sinaga had been targeting men for at least 10 years.
