Student fought back after waking during assault and was treated by police as a suspect

The student who exposed the serial rapist Reynhard Sinaga has said he feared he had killed him after he woke and fought back when he found he was being abused.

Sinaga, 36, was jailed this month for a minimum of 30 years for 136 rapes against dozens of young men in Manchester. Police believe he would have carried on offending had one of his victims not woken up during an attack and called 999.

Photos, videos and ‘trophy items’ suggest ‘Britain’s worst ever rapist’ attacked 195 men between 2005 and 2017

Police in Manchester believe the PhD student dubbed “Britain’s worst ever rapist” may have attacked men as far back as 2005 – and have admitted he called them at least twice to help evict men from his flat.

Reynhard Sinaga, 36, from Indonesia, posed as a “good Samaritan” outside clubs in central Manchester, inviting men back to his flat for a drink or to charge their phones, before slipping the date rape drug gamma-hydroxybutyrate (GHB) into their drink. He then recorded himself raping them, sometimes for hours at a time.

A man described as “Britain’s most prolific rapist” will never be safe to be released, a court has heard, as he was jailed for a minimum of 30 years after being found guilty of raping or sexually assaulting 48 young men in Manchester.

Reynhard Sinaga, 36, a mature student from Indonesia, is thought by police to have abused at least 195 men over two-and-a-half years after luring them to his flat under the guise of being a “good samaritan”, drugging his victims and then attacking them after they passed out.
