The most prolific rapist in British legal history has been convicted of rape and sexual assaults against 48 men.
Sentenced to multiple life sentences, Reynhard Sinaga will serve at least 30 years.
Many men only discovered they had been raped when the police contacted them.
The serial rapist targeted young males who were often students, alone or drunk.
His MO seems to have been to lure victims to his flat under false pretences, drug them with illegal date rape substance GHB, rape them and then record his sex attacks on his smartphone.
Over the last two years, there have been four criminal trials, nearly 160 counts of rape and sexual assaults against 48 men.
But police believe the serial rapist may have attacked more than 190 men; 79 of whom are yet to be identified.
Many victims may have no memory of being raped or subjected to sexual assaults.
