Cross-Border Operation Leads to Arrests
Ugandan and Kenyan police have arrested three suspects in connection with the murder of Dr. Mutiso, who was fatally shot in Nairobi on July 29, 2026, according to reports from The Independent Uganda and Daily Monitor.
The Directorate of Criminal Investigations (DCI) in Kenya said that acting on forensic analysis, detectives traced two suspects to Kyanja Heights flats in the Nakawa suburb of Kampala, where they were arrested with the help of the Uganda Police Force. The DCI identified them as Police Constable Bett Kiplangat Collins, service number 118491, attached to Thogoto Police Station, and Pius Muiru Mbugua, a civilian.
The agency said the two had sneaked into Uganda illegally after the murder. They are being held at Jinja Road Police Station pending an escorted return to Nairobi.
A third suspect, Samuel Karanja Gathoni, who the DCI says also goes by the alias “Lawyer”, was intercepted earlier by the same team within the Langata Multi-Media area as he headed towards Ongata Rongai.
Alleged Roles in the Murder
According to the DCI, investigations have established that PC Bett was tasked with surveillance and acted as co-driver to Daniel Mwangi Njoroge, described by detectives as a central organiser of the operation and the driver of a Land Cruiser Prado registration number KDH 600A. That vehicle, the agency says, was used to box in the Uber in which Dr Mutiso was travelling on the morning of 29 July 2026 in Upper Hill, Nairobi, moments before she was fatally shot.
Detectives further allege that Mbugua served as the link between the execution team and the person who contracted it, acting as paymaster and moving money for logistics and the movement of the hit squad.
The National Police Service acknowledged the support of the Uganda Police Force, saying its cooperation made the raid, the arrests and the secure detention of the suspects possible.
The DCI said the suspects held in Uganda are being prepared for escort back to Kenya, where all three will be processed and arraigned in accordance with the law.
Separate Incident: Police Officer Arrested for Fatal Shooting
In a separate development, the Uganda Police Force has arrested one of its own officers following the fatal shooting of a boda-boda rider who allegedly attempted to pass through a secured area during the monthly National Cleaning Day exercise in Ndejje, Wakiso District.
The suspect, identified as Police Constable Allan Okello, is currently in custody as homicide detectives investigate the circumstances surrounding the Saturday morning incident within Katwe Police Division.
According to Police Spokesperson ACP Rusoke Kituuma, the fatal shooting occurred at approximately 7:30 m. at Ndejje Kanaaba, where officers from Ndejje Police Station had been deployed to provide security and enforce compliance during the community cleaning initiative.
Preliminary police reports indicate that the deceased, identified via his National Identification Card as 38-year-old Ronald Juuko Kizito, was riding his motorcycle when he attempted to force his way through a barricaded section. A confrontation ensued, during which Constable Okello discharged his firearm, striking and killing the rider.
"The Uganda Police Force has registered and commenced investigations into a shooting incident that occurred on 29 August 2026 at around 7:30 m. at Ndejje Kanaaba, within Katwe Police Division," ACP Kituuma said in a statement issued on Saturday. "The officer has been arrested, and investigations are underway to establish the circumstances under which he discharged his firearm, resulting in the death of the rider."
Addressing the conduct of enforcement personnel during public exercises, ACP Kituuma emphasized the legal boundaries governing the use of force by security officers. He cautioned that while police officers are legally mandated to maintain public order and protect life and property, any use of force must be lawful, necessary, and proportionate. He outlined exemptions for emergency services, medical personnel, patients, journalists, foreign tourists, and cross-border transport vehicles, which require proper identification to security personnel.
Police management also noted that National Cleaning Day is held on the last Saturday of every month between 7:00 m. and 10:00 , and the exercise imposes temporary restrictions on vehicular movement and commercial activities.
