The Scholar Who Preyed in the Shadows

When 28-year-old Zhenhao Zou arrived in the UK in 2017 to pursue higher education, he appeared to be just another ambitious international student. Originally from China, Zou moved to Belfast to study at Queen’s University before heading to London in 2019 for a master’s degree. Eventually, he began a PhD at University College London (UCL), a prestigious institution that would become the backdrop for a horrifying saga of predation and deceit.

Beneath the polished veneer of an affluent academic with a taste for luxury lurked a monster. Zou, who lived in high-end apartments and spent lavishly on designer clothing and cosmetic procedures, concealed a terrifying double life. Over the course of several years, he would go on to become one of Britain’s most dangerous sexual predators.

A Trail of Victims Across Two Countries

Between 2019 and 2024, Zou orchestrated a chilling spree of sexual assaults—reportedly 60 in total—preying on unsuspecting women in both the UK and China. His method was calculated and sinister: he prowled dating apps and social media under the pseudonym “Pakho,” lured victims to his residences, and drugged them with a toxic cocktail of GHB, MDMA, ketamine, and Xanax before violating them in their unconscious state.

The scale of his crimes was staggering. Investigators unearthed 58 video recordings, amounting to approximately 1,660 hours of harrowing footage documenting his attacks. The Metropolitan Police described his offenses as “insidious,” warning that many victims may never even realize they were assaulted.

“This man may well turn out to be one of the most prolific sexual predators that we've ever seen in this country,” Commander Kevin Southworth declared.

The Evidence That Sealed His Fate

When police finally raided Zou’s apartment, they uncovered a nightmare. The sheer magnitude of evidence left no room for doubt—an archive of recorded assaults, a “trophy box” filled with victims’ jewellery, and clothing, and a “rape kit” stocked with drugs used to render women powerless.

Zou’s crimes bear an eerie resemblance to other methodically documented cases of abuse, such as the Gisèle Pelicot case in France, where a woman was subjected to a decade of orchestrated assaults. Like Pelicot’s abusers, Zou wielded secrecy as a weapon, turning his victims into unwitting prisoners of their own silence. His crimes were not crimes of passion—they were premeditated, sustained, and sadistically recorded for his own gratification.

Jurors in Zou’s trial had to endure the unthinkable—hours of damning footage where victims, some barely conscious, pleaded for him to stop before succumbing to the drugs in their system. The recordings, described as “soul-crushing” by prosecutors, left no room for ambiguity about the systematic and depraved nature of his assaults.

Manipulation and Deception

Throughout the trial, Zou attempted to rewrite reality. He claimed his encounters were consensual, a sickening attempt to recast his crimes as elaborate role-play scenarios—another parallel with the Pelicot case. Many of the men in the Gisèle Pelicot case claimed they did not know she was unconscious, though the extent of their knowledge and complicity varied. Some argued that they believed she was a willing participant, while others insisted they were unaware of the orchestrated nature of the assaults.

In both cases, the overwhelming weight of evidence crushed any illusion of consent.

Prosecutor Catherine Farrelly KC described Zou as a “wolf in sheep’s clothing”—a predator who wore a mask of charm and intelligence but, beneath the surface, was ruthless and calculating. Zou himself admitted to consuming extreme pornography depicting unconscious women—an obsession that prosecutors argued was not fantasy but a blueprint for his real-life horrors.

The Victims Speak Out

One of Zou’s victims courageously stepped forward to recount the nightmare she endured. On May 18, 2023, she met Zou at his home in Elephant and Castle, London. After a night of heavy drinking, she attempted to leave—but Zou had no intention of letting her go. He dragged her back inside, forced her to consume more alcohol, and later, she was found unconscious. Video evidence confirmed that she had been assaulted while incapacitated.

Another victim’s voice, caught on a chilling recording, trembled as she pleaded, "I really don’t want… I beg you, don’t do this," before the drugs took hold and she slipped into unconsciousness.

Justice and Aftermath

On June 19, 2025, Zou will finally face sentencing, convicted on multiple charges, including 11 counts of rape, three counts of voyeurism, false imprisonment, possession of extreme pornographic material, and three counts of possessing controlled drugs with intent to commit sexual offenses.

But the full extent of his predation may never be known. Following the trial, at least one more woman has come forward with concerns about Zou. The Metropolitan Police have launched an international appeal, urging other potential victims—especially within the Chinese student community in London—to break their silence.

A Case That Shook the UK

Zhenhao Zou’s crimes are a terrifying reminder of how sexual predators can operate undetected for years, hiding in plain sight. His ability to evade justice, despite leaving behind mountains of incriminating evidence, exposes the dangerous illusion of safety that wealth, intelligence, and respectability can create.

As Zou awaits his fate, investigators continue the search for more victims. His case serves as a grim testament to the darkness that can lurk behind even the most unassuming facades—and a call to action to ensure that survivors are heard, believed, and given the justice they deserve.
