The 'Ruiru Vampire' mystery: Bites that have turned bustling town into a fear zone

The moment darkness falls over parts of Ruiru, deserted footpaths and dimly lit streets take on a sinister reputation.

The moment darkness falls over parts of Ruiru, deserted footpaths and dimly lit streets take on a sinister reputation.

Residents hurry home before nightfall. Boda boda riders avoid isolated routes. Traders close their businesses early, while parents repeatedly call their children indoors before darkness fully descends.

As silence engulfs the bustling town, anxious whispers begin.

“Usitoke nje usiku... vampire bado hajakamatwa.” (Don’t go out at night... the vampire is still at large.)

For weeks, residents of Gitothua Ward and neighbouring estates have lived under the shadow of an elusive attacker they have nicknamed the “Ruiru Vampire”, a mysterious man who allegedly ambushes unsuspecting victims, robs them and leaves them with horrifying bite wounds on their lips, fingers, backs and even faces before disappearing into the darkness.

The bizarre attacks have transformed one of Kenya’s fastest-growing towns into a community gripped by fear, suspicion and rumour.

Ironically, this is not the first time Ruiru has captured national attention for an unusual reputation. More than two decades ago, the late Kikuyu secular musician Jimmy Wayuni immortalised the town in his controversial hit song Airitu a Ruiru, warning men about women he portrayed as cunning and manipulative.

Today, however, Ruiru’s reputation is linked to a very different conversation. Instead of the debates sparked by Wayuni’s song, residents now speak in hushed tones about the alleged “vampire” said to be terrorising the streets after dark.

The fear has become so pervasive that suspicion now hangs over every stranger.

False alarm

Last Saturday, an angry mob descended on a 35-year-old man after word spread that the elusive attacker had finally been captured. The crowd beat him before police intervened.

But as details slowly emerged, residents realised the man may not have been the serial attacker after all.

Instead, he had allegedly become involved in a violent confrontation with a woman after the two spent the night together at a local lodging. Whether he is linked to the earlier attacks remains under police investigation.

Meanwhile, the real attacker if indeed all the incidents are connected remains at large.

According to a close friend of the injured woman, the victim is a mother of three children, with her eldest child currently in Grade Eight. She and the suspect reportedly booked a room on Friday night, where they spent hours drinking and merry-making.

The following morning, shortly before checkout time, the woman allegedly woke the man so he could clear the accommodation bill.

The man, who reportedly appeared intoxicated, reached for his phone only to discover that more than Sh80,000 had allegedly been transferred from his account to an unknown recipient. He confronted the woman.

What began as a disagreement quickly escalated into violence.

Paul Mbugua (not his real name), a mechanic working near the lodging, recalls hearing desperate screams coming from one of the rooms. “We rushed there thinking it was an ordinary domestic quarrel,” he says.

“When we got inside, we found the man holding the woman tightly with his mouth firmly locked onto her lips. At first we thought they were deeply kissing, but when she continued crying we realised he was actually biting her.”

Mbugua says several people tried pulling the man away, but he appeared unusually aggressive and refused to release the woman. “The woman was also holding his private parts as she desperately struggled to free herself. We poured water on him and kicked him before he finally released her. By then part of her lower lip had already been torn off.”

The horrifying sight triggered panic.

“People immediately started shouting that we had finally caught the vampire who has been terrorising Ruiru residents,” Mbugua recalls.

Police officers arrived shortly afterwards and rescued the suspect from the angry mob before arresting him.

The woman was rushed to Ruiru Level Four Hospital before doctors referred her to Thika Level Five Hospital for specialised treatment.

By Tuesday, she was still waiting to be reviewed by specialists who are expected to perform reconstructive surgery on her badly damaged lower lip.

Similar attacks

Her injuries bear striking similarities to those suffered by victims attacked over the past few weeks.

Among them is Daniel Ndegwa, who was reportedly attacked on July 11 at about 9pm while walking to a nearby shopping centre.

According to reports, a stranger confronted him and demanded his mobile phone before a struggle ensued. During the confrontation, the attacker allegedly bit one of his fingers and seriously injured his left hand. A friend who was accompanying him was also reportedly bitten.

In another chilling incident, a victim suffered severe facial injuries after the attacker allegedly bit off part of his cheek before disappearing into the darkness. He sought treatment at Kenyatta University Teaching, Referral and Research Hospital and is still awaiting specialised reconstructive surgery.

Residents say nearly every attack follows the same disturbing pattern.

The assailant strikes after dark, he targets pedestrians,he bites with unusual brutality, then vanishes before anyone can apprehend him. The attacks have dramatically changed life in Gitothua Ward.

Women operating businesses late into the evening now close several hours earlier than usual. Parents no longer send children to nearby shops after sunset. Evening walks have disappeared, while boda boda riders increasingly avoid poorly lit roads for fear of encountering the attacker. “It is heartbreaking,” says Wambui, a trader.

“We now close our businesses much earlier because nobody wants to risk meeting this man. We need more police patrols before somebody loses their life,” she adds.

Her concerns are echoed by Severino Githinji, who says fear has become part of everyday life.

“People no longer move freely once darkness falls. We are appealing to the government to increase security patrols, install proper street lights in dark sections of the estates and ensure whoever is behind these attacks is arrested immediately before another innocent resident suffers.”

Families of victims say the attacks have left their loved ones not only nursing painful physical injuries, but also battling emotional trauma.

Police probe

Ruiru Sub-County Police Commander Charles Kibathi confirmed that the only suspect currently in custody is the man arrested on Saturday.

“The suspect and the female victim were taken to hospital for treatment and investigations are ongoing,” Kibathi said.

He added that detectives are trying to establish whether the suspect is connected to the earlier attacks reported in Gitothua Ward.

Kibathi urged residents not to take the law into their own hands, saying investigations are ongoing and police are pursuing every lead.

However, some residents insist the arrested man is not the elusive attacker who has spread fear across the town.

“The man who bit the lady is someone we know,” says trader Nelly Muthoni.

“What happened between him and the woman was a disagreement after they spent the night together. That is completely different from the attacks residents have been reporting.”

Whether Saturday’s incident was simply a domestic dispute that turned violent or whether detectives have finally arrested the man behind weeks of terror remains unanswered.

Long before the “Ruiru Vampire” became the latest phrase on everyone’s lips, another story about Ruiru had entered Kenya’s popular culture.

Celebrated Kikuyu secular musician Wayuni’s hit “Airitu a Ruiru”, blended humour, satire and social commentary, warning men about women he described as cunning, materialistic and manipulative.

One of the song’s most memorable metaphors suggested that some women “eat meat before it is put on the fire,” symbolising impatience and opportunism.

Wayuni later explained that the song was inspired by his own experiences and observations and was never intended as an attack on all women from Ruiru.

At the time, Ruiru was rapidly transforming into one of Kenya’s busiest industrial and residential towns, attracting thousands of workers from Nairobi and neighbouring counties. Along with rapid urban growth came a reputation fairly or unfairly for vibrant nightlife and transactional relationships, making the town a fitting backdrop for Wayuni’s social satire.

The song divided opinion.

Some listeners laughed.

Others, particularly women from Ruiru, felt unfairly stereotyped.

Yet despite the controversy, it became one of Wayuni’s signature classics and remains popular years after his death in a road accident along the Thika Superhighway in May 2020.

Today, Ruiru finds itself battling a very different reputation.

Instead of being remembered for the women immortalised in a famous song, it is increasingly being associated with fear, gruesome attacks and sleepless nights.

Residents say the solution lies in swift police action, increased patrols, improved street lighting and the immediate arrest of whoever is behind the terrifying attacks before another family is forced to live with the physical and emotional scars left by the mysterious “Ruiru Vampire.”

Until then, as darkness falls over Gitothua and surrounding estates, doors will continue closing early, deserted streets will continue feeding rumours, and one unsettling question will linger in every household:

Who is the Ruiru Vampire, and who will be the next victim if he is not stopped.
