WORLD'S worst rapist Reynhard Sinaga spent a decade partying in the UK funded by a "very rich" family in Indonesia who didn't know he was gay and begged him to settle down and marry a woman.

The depraved sex fiend drugged and assaulted up to 195 men at his flat near Manchester city centre's gay village during a two-year reign of terror.

Greater Manchester Police have described the case as Britain's biggest ever rape investigation and Sinaga's conviction is believed to include the highest number of victims attacked by one man anywhere in the world.

Sinaga targeted tipsy revellers as they poured out of nearby nightclubs then filmed himself raping his unconscious victims in the seedy lair on a makeshift bed.

The 36-year-old PhD student blew his rich property tycoon dad's money on partying as he enjoyed Manchester's liberal and tolerant atmosphere to homosexuality.

But his openly gay lifestyle was a world away from the strict Catholic upbringing he had in Indonesia where homosexuality is frowned upon and illegal in some states.

His parents Saibun and Normawaty didn't even know their son was gay and tried to pester him into getting married.

A former friend told The Sun: "His relationship with his family wasn’t good.

"They found him odd even before he came out as gay. And he didn’t come out to them.

“I think he liked to get people’s attention to compensate.

“He used to say he was depressed because his parents tried to make him meet some girl from his country.

“The relationship wasn’t good because they wanted him to marry and have a family. We used to tell him to cheer up because he could be himself in Manchester.

“Everyone felt sorry for him not being able to be himself with his family.

"He used to change his hair and clothes to go home and see them.”

13 Sinaga's wealthy parents paid for him to study for three postgraduate courses in the UK

Sinaga grew up in a mansion in the centre of Jakarta with a house brimming with maids and drivers.

But the Spice Girls-obsessed fiend struggled to be himself with his family, who found him "odd" and wanted him to meet a girl from Indonesia to wed.

Instead, Sinaga moved to the UK as a student in 2007 when he was 24 where he studied a masters in planning at Manchester University.

The bright student then completed another masters in sociology before enrolling in a PhD in geography at Leeds University, commuting there from Manchester.

His thesis was titled "Sexuality and everyday transnationalism: South Asian gay and bisexual men in Manchester".

He was suspended from the university on his arrest and will not be allowed to complete his doctorate.

Sinaga had begun to explore his sexuality as a student and had a string of boyfriends during his time living in Manchester.

A pal said: "He would go to the gay village with us, but he used to tell us that during the week he would go to other clubs around. He liked masculine guys."

But while living near Manchester's clubbing scene, Sinaga would watch as his targets - usually straight men - poured in and out of nearby bars Factory and Fifth Avenue.

And the rapist would prowl the streets outside the Manchester clubs in the early hours looking for lone, drunk men to attack.

He even played "Top Trumps" of people he raped by keeping screenshots of his victims' social media profiles after checking their IDs.

He also boasted of using his “secret poison” to make young, straight men “fall in love” with him.

In one chilling encounter captured on CCTV, he left his flat and returned with a victim just 60 seconds later.

He was finally arrested after a hero rugby player battered him after he woke up naked to find Sinaga molesting him.

The teenager beat the predator so violently he left the rapist with a bleed on the brain and blood splattered around the flat.

Two victims attempt suicide after abuse revealed Two of Sinaga's victims attempted to take their own lives after suffering severe depression when they found out they had been violated. Most of the 48 confirmed victims - of whom 45 were heterosexual and 26 were students - thought the defendant had acted as a Good Samaritan and many felt guilty after being sick in his flat. One victim thought Sinaga had been "really nice" and said he looked after him when he found him lying on the ground near a hotel. Another complainant was sitting on the kerbside after the battery on his mobile phone was drained and he was approached by Sinaga. The defendant invited him to his apartment to charge the device but instead went on to drug and sexually violate him on camera. Others felt they had undergone a "weird experience" but had no real concerns or suspicions. Two victims attempted suicide while others turned to drink or were forced to quit jobs and studies due to their trauma.

Sinaga then spun a web of lies after being stretchered to hospital - meaning the victim, then aged 18, was arrested on suspicion of assault.

But the blundering rapist had accidentally left an iPhone 4 in the teen's back pocket containing gruesome videos of him attacking his drugged victims.

After he tried to "snatch" the mobile, which he had held in one hand while molesting the men, cops realised they were dealing with a sinister monster.

Police raced to twisted Sinaga's lair where they discovered another mobile - this time "propped to side” to capture rapes “in profile”.

Prosecutor Iain Simkin told Manchester Crown Court if Sinaga had not “recorded himself” raping his victims “nobody might ever have found out.”

His gruesome crimes are said to have come as a shock to his family, who regularly visited Sinaga in the UK and even saw him at least once in prison.

The court was told they knew nothing of the "cold, cunning and calculated rapist" but it is understood they paid for a top QC for his trial.

Family friend Sahat Sinaga, a palm oil tycoon based in Jakarta, told The Sun: "This is shocking news for them to have to face. They wouldn’t know all this.

“They will be shocked, deeply shocked.”

Sicko's boasts after rape attacks Sinaga boasted about his crimes to friends on WhatsApp and social media. In January 2015, after raping a 19-year-old man he bragged: "SuperRey saves straight boys from their monstrous girlfriend". He then sent a photograph of the unconscious victim and added: "Finally I can see the inside of Rey’s room, I was always forbidden to go behind the magic door hahaha. "Then we were joking male dead body were piling under the bed haha." On social media, he boasted of using his “secret poison” to make young, straight men “fall in love” with him. He wrote: "Manchester is a magical city. City of gay romance, city of gay love. Take a sip of my secret poison. It’ll make you fall in love."

His family and friends in Indonesia have deleted Sinaga from their social media accounts as they attempt to distance themselves from the prolific predator.

On Monday Sinaga was caged for life after being found guilty of 159 charges against 48 men - aged between 17 and 36 - between January 2015 and June 2017.

But cops found footage and other evidence of up to 195 victims on laptops and the two iPhones.

Most of his victims had no clue they had been attacked. Only two already knew they had been raped when they were approached by police.

Police have been unable to identify 70 victims and it is believed dozens more could now come forward following his conviction.

Assistant Chief Constable Mabs Hussain of Greater Manchester Police urged anyone who believes they may have been a victim of Sinaga to come forward.

He added: "We believe Reynhard Sinaga is the UK's most prolific rapist and the reason I say that is because on the information and evidence we suspect there are in total 190 victims approximately who have been involved.

"We can't give you a definitive figure for obvious reasons. Forty-eight of them have supported a criminal prosecution.

"Of that 190 there are approximately 70 that we are still yet to identify and the reason we have still yet to identify them is despite our best efforts, and the investigation team working tirelessly to piece together the information, we have been unable to identify who each individual is to speak to them. There is still some work for us to do."
