It is believed that Reinhard Sinaga is the “most prolific rapist” ever in the UK.

Princess Street is never calm in the heart of downtown Manchester.

When you follow it down from Albert Square’s magnificent Victorian town hall, through pubs, cafes, restaurants, and abandoned silk factories, you can enter the borders of two of the city’s most popular destinations – Chinatown and Gay Village.

You come over to a stretch of road bordered by nightclubs-Factory, Fifth, Joshua Brooks-a, a large part of the vibrant nightlife of the area.

The road is also a popular residential area for students with its proximity to two of the city’s universities.

Reinhard Sinaga, a 36-year-old graduate student, has been living in a rented flat just a few moments ‘ walks from Factory Nightclub for more than seven years, calling this his home.

Sinaga was a lifelong pupil, originally from Indonesia. He already had four degrees and was a doctoral student. He’s been a serial sex offender by night.

He has been found guilty of drug abuse and abuse. Sexually assaulting 48 men, but police believe that at least 190 victims are among them.

Police can be so sure about these figures because Sinaga filmed his assaults and retrieved what police call “trophies”-items or stolen information from his victims.

Usually, Sinaga approached his street victims. The rapist operated around his flat in a small area. His targets were men who had been drinking mostly in their late teens or early twenties, often in nearby nightclubs.

Some were going home, and others were separated from friends.

Many were too drunk to remember Sinaga’s conversation, but there was no sign of a sexual motive for those who did it. Sinaga used different pretexts to attract each of them to his flat.

Some victims may recall having a drink and then blacking out.

Sinaga portrayed herself as a flamboyant, ecclesiastical scholar using the nickname “posh spice.” He seemed visually unthreatening to be a thin man of modest build and short stature. Several victims are reminding him to smile a lot.

It was this apparent harmlessness that allowed Sinaga to pose as a “good Samaritan,” coaxing men back to the flat.

We learn about the benevolent image Sinaga generated because the police were witnessed by thousands of victims, 48 of whom appeared in court in four courts.

The vast majority of the victims who went to court were male. Ian Rushton of the Crown Prosecutor’s Service said that he felt Sinaga took “extreme joy in preying on heterosexual men.”

At the time, most of his victims were living in London, and when they were stabbed, 26 were students in all.

Their accounts explain the operation of Sinaga.

Another waited outside the nightclub of Fifth Avenue for his partner-since renamed Fifth Manchester-when a “small Asian man” approached him who seemed innocuous.

The guy was welcomed back to the flat of Sinaga to wait for his mother, but after a shot of clear liquid to drink, he recalled nothing more.

Another man described a “young Asian gentleman’s style.” He said that he had a “vague memory,” meaning that my phone was dead, and I was trying to get a cab, but the taxis stopped me.”

He added: “I think I can remember a conversation along the lines of ‘ Would you like to come in and charge your phone and chat quickly, ‘” he told the court.

Sinaga “didn’t seem like an intimidating character” to him and seemed to be “a genuine, motivated person” with interest in academic research during their conversations in the apartment.

The man told the court that he couldn’t remember “a single thing until the next morning” soon after a drink was offered.

He left just five minutes of waking up, lost, and disoriented.

He had no idea, like almost any victim, that he had been assaulted before police approached him.

One survivor recalled being seated in a taxi outside a club by his parents. His next memory was in a strange apartment to wake up.

As he asked Sinaga what had happened, after noticing him lying on the street, he mentioned providing care and shelter.

Another victim believed that Sinaga was “really nice and cared for him.”

Upon waking up in the flat, one suspect, a teenage university student, managed to get Sinaga’s mobile number as a precaution and then worried that something might have been taken from him.

Sinaga identified himself as a “good Samaritan” who found him dead on the pavement as he called to inquire for more information about what happened.

Another man recalled waking up on the floor, wrapped in a blanket, before thanking the owner of the flat for allowing him to stay there.

He did not suspect anything, although the individual “refused to give me personal details” to help with a claim for a missing mobile phone policy. The phone was later recovered by police from Sinaga’s house, like many others taken from their owners.

Upon regaining consciousness, multiple patients felt incredibly miserable, often nude, and coated in blood. Sinaga, who at the time was unknown to them, had given his victims a drug-almost probably GHB-that left them unconscious before he assaulted them.

One victim, who woke up naked on Sinaga’s floor feeling nauseous and panic-stricken, concluded that he had been drugged, telling his fiancé that suspicion, but not the condition in which he was awakened.

Another man, who had been told he should sleep on the floor, decided to wake up twice at night to get sick on one occasion.

He recalled that he was unable to move his arms on one of the occasions and could feel penetrated before going out again.

Before leaving, he spoke briefly with Sinaga in the morning. Until they approached him, he did not report what happened to the police.

It was the most significant prosecution into rape in the history of the UK.

Police found more than 100 men from the answers in Sinaga’s apartment. But 70 men’s identities have not been established, and the police are now appealing to anyone who believes Sinaga might have abused them.

Ian Rushton of the CPS says Sinaga is potential “anywhere in the country,” the most notorious known rapist.
