A 46-year-old man, Joseph Kamau Wainaina, died at the Kiambaa Police Post in Kiambu County, Kenya, on Sunday, September 20, 2026. According to police reports, Wainaina got trapped in the metal grills of the report office while trying to force his way through them. Police Constable Paul Tota, a report office officer at the station, filed the incident report at 2:55 am on the day of the incident.
The deceased's sister, Nancy Wairimu Wainaina, provided insight into her brother's medical history, stating that he had a long-standing history of mental illness and had been experiencing hallucinations prior to the incident. However, she did not elaborate further on the circumstances that led him to the police post. The Officer Commanding Station at Karuri Police Station, alongside other officials, visited the scene to investigate the incident.
Following the report, detectives from the Directorate of Criminal Investigations (DCI) Kiambaa and Crime Scene Investigation (CSI) officers from Kiambu processed the scene. Wainaina's body was then transferred to the Kiambu Level 5 Hospital mortuary, where it awaits a post-mortem examination. The case remains under investigation by DCI Kiambaa, with an autopsy pending.
This incident has drawn attention to a pattern of deaths involving individuals at police facilities across Kenya. In May 2026, Benard Nyakwana Omae, a young Nairobi man, was found dead at Kibra Police Station after reportedly being arrested by officers from the Rapid Deployment Unit (RDU) on May 20 in connection with an alleged motorcycle theft.
There have been other reported cases of deaths in police custody in Kenya. In October 2025, 40-year-old Allan Kamau was found dead inside a cell at Komomwamu Police Post in Kuria West, Migori County, with an autopsy confirming that asphyxiation was the cause of death. In June 2025, Albert Omondi Ojwang died while in detention at Nairobi's Central Police Station, sparking public outrage and leading to the arrest of the Officer Commanding Station and three police officers.
The incident at Kiambaa Police Station has raised concerns about the safety and security of individuals in police custody. The Directorate of Criminal Investigations (DCI) Kiambaa is continuing to investigate the circumstances surrounding Wainaina's death. The post-mortem examination at Kiambu Level 5 Hospital mortuary is pending, and the case is ongoing.
The Kenyan police service has faced scrutiny over the years regarding the handling of suspects in custody. Human rights organisations have called for improved training and accountability within the police force to prevent such incidents. The Ministry of Interior has also been urged to investigate the circumstances of deaths in police custody and take necessary actions to prevent future occurrences.
