A prime suspect has been apprehended in Kiambu County in connection with the murder of three men, while separate investigations into other homicides are underway across Kenya.

• The suspect is linked to the killings of Kennedy Mambo, John Kamau, and Cyrus Muchiri found deceased on July 21, 2026.
• Detectives from the Directorate of Criminal Investigations (DCI) in Kiambu East are leading the investigation after arresting the suspect in Nyeri County.
• Preliminary findings suggest the motive stemmed from the suspect's dismissal from his job as a caretaker over alleged theft at a construction site.

Nairobi Governor Johnson Sakaja has announced the upcoming training of 2,500 officers for a new Nairobi Metropolitan Police Unit designed to bolster security in the capital city.

• 2,500 officers will be trained from both the Nairobi County Inspectorate and the National Police Service.
