More potential victims of serial rapist Reynhard Sinaga have contacted police following his conviction for sexual offences against at least 48 men.
Sinaga was unmasked yesterday after being sentenced to at least 30 years in prison.
He has been found guilty of a total of 159 offences committed between January 2015 and May 2017.
These include 136 counts of rape, 13 counts of sexual assault, eight counts of attempted rape and two counts of assault by penetration.
Police have linked Sinaga to more than 190 potential victims and encouraged others who suspect they may have been targeted by him to contact authorities.
Greater Manchester Police said since his sentencing, in which he was described as an "evil serial sexual predator", there have been "multiple calls" to its incident room.
The force has not confirmed a specific number but said some the calls were potentially further victims of Sinaga, who is Britain's most prolific serial rapist.
The 36-year-old went out in the early hours of the morning searching for men near his flat in Manchester.
Manchester Crown Court was told how he posed as a Good Samaritan who offered them a floor to sleep on or promised them more drink.
Judge Suzanne Goddard QC, who told the court his total number of potential victims was 195, told the defendant: "You are an evil serial sexual predator who has preyed upon young men who came into the city centre wanting nothing more than a good night out with their friends.
"One of your victims described you as a monster. The scale and enormity of your offending confirms this as an accurate description."
It is thought he laced victims drinks with GHB, also known as liquid ecstasy, and many left his apartment unaware that they had been violated.
His charges were split across four different trials, the last of which finished yesterday.
Potential victims can contact Greater Manchester Police by calling 0800 092 0410 or visiting the force's website.
