Detectives investigating the murder of Dr Victoria Nthunya Mutiso have arrested three more suspects in a coordinated operation conducted in Nairobi and Kampala.
The Directorate of Criminal Investigations (DCI) said the latest arrests followed forensic analysis by a specialised team drawn from its Crime Research and Intelligence Bureau (CRIB), Operations Directorate and Homicide Bureau.
Two of the suspects were arrested in Kampala after detectives, working with the Uganda Police Force, raided Kyanja Heights flats in the Nakawa suburb.

The suspects were identified as Police Constable Bett Kiplangat Collins, attached to Thogoto Police Station, and civilian Pius Muiru Mbugua.
According to the DCI, the two allegedly entered Uganda illegally after Dr Mutiso was killed. They are currently being held at Jinja Road Police Station as arrangements are made for their escorted return to Kenya.
The DCI also disclosed that a third suspect, Samuel Karanja Gathoni, alias “Lawyer”, was intercepted in Nairobi within the Langata Multi-Media area while travelling towards Ongata Rongai.
Investigators allege that PC Bett played a surveillance role in the operation and acted as co-driver to Daniel Mwangi Njoroge, whom detectives have described as a central organiser of the alleged operation.
Njoroge was allegedly driving a Land Cruiser Prado, registration number KDH 600A, which investigators say was used to box in the Uber vehicle carrying Dr Mutiso shortly before she was shot dead.
Dr Mutiso was fatally shot on the morning of July 29, 2026, in Nairobi’s Upper Hill area.
The DCI further alleges that Muiru Mbugua acted as a key link between the alleged execution team and the person who contracted them.
According to investigators, Mbugua served as a paymaster, handling money for logistics and facilitating the movement of the alleged hit team.
The three suspects are expected to be returned to Kenya, where they will be processed and arraigned in court in accordance with the law.
The latest arrests come as investigators continue to pursue leads into the circumstances surrounding Dr Mutiso’s killing.
The DCI said the suspects’ movement to Uganda had delayed aspects of the investigation but did not bring it to a halt.
The agency also thanked the family, friends and relatives of Dr Mutiso, as well as members of the public, for their patience and support during the investigation.
The DCI dismissed earlier claims that suspects had been arrested and subsequently released or that security officials had facilitated their escape, describing the allegations as false and politically motivated.
The agency maintained that the latest arrests in Kampala demonstrate that investigations remained active and that detectives had continued pursuing those suspected of involvement in the killing.
