NAIROBI, Kenya — The Directorate of Criminal Investigations (DCI) has rejected allegations by former Deputy President Rigathi Gachagua concerning the handling of criminal investigations, describing them as “baseless”, “ridiculous” and “wholly without foundation”.
In a statement issued on Tuesday, August 11, the DCI said it had taken note of what it termed a “litany of baseless and unsubstantiated allegations” touching on the agency.
The Directorate challenged Gachagua and others making the claims to provide credible evidence rather than relying on unverified allegations that it said could undermine public confidence in law enforcement.
“The DCI categorically states that it does not sanction, facilitate, conceal, or participate in criminal conduct of any kind,” the agency said.
It added that its mandate is to investigate serious and complex crimes, gather evidence and present cases to prosecutorial and judicial authorities in accordance with the Constitution, the law and established investigative procedures.
DCI denies political interference
The agency also rejected suggestions that political considerations influence its investigations.
The DCI said cases involving alleged abductions, disappearances, deaths, police shootings, attacks on journalists and other serious offences are investigated where they fall within its mandate and where evidence is available.
“No individual is above the law,” the Directorate said, adding that neither political affiliation nor public prominence influences how criminal investigations are conducted.
The DCI further rejected suggestions that its investigations were being undertaken to serve political interests, saying investigative outcomes and subsequent decisions were guided by evidence and the law.
The agency said it would not disclose sensitive operational information through the media where doing so could compromise ongoing investigations.
DCI gives update on murder investigations
In defending its record, the Directorate highlighted progress in several high-profile investigations that have attracted public attention.
On the murder of Reverend Julius Ndumia Ngari, the DCI said two suspects, Felix Odinga Okumu and Berryly Nafua Atenyo, had been arrested and arraigned before the Nakuru Law Courts.
The agency also said four armed gangsters were fatally shot during an intelligence-led operation along the Eldoret-Kiplombe-Soy Road after allegedly engaging detectives in a gun battle.
A Falcon pistol was recovered at the scene, according to the DCI.
The Directorate said forensic analysis and other evidence had linked the gang to the robbery with violence incident in which the PCEA reverend was killed, as well as to other suspected criminal activities in the region.
Update on Dr Victoria Mutiso murder
The DCI also provided an update on the investigation into the killing of Dr Victoria Nthunya Mutiso, saying “tremendous progress” had been made since its previous briefing on August 7.
It said the remaining suspects were being actively pursued and would be arrested and taken to court.
The case has attracted significant public and political attention, with Gachagua previously raising questions over the investigation and alleged involvement of police officers. The DCI has separately outlined its progress in the case.
Suspect arrested over businessman’s murder
The Directorate also disclosed that detectives in Cheptais had arrested Oscar Koech Sakong, who is suspected of involvement in the murder of 61-year-old businessman Nathan Masai Wasama.
According to the DCI, Wasama was shot dead at his shop at Tuikut Trading Centre in Sasur Location, Cheptais Sub-County, on the night of August 8, 2026.
Sakong was taken to Sirisia Police Station as detectives continued investigations to establish the motive and identify and apprehend other suspects.
The DCI said all available investigative resources had been deployed to bring those responsible to justice.
DCI warns against politicising deaths
The Directorate also criticised what it described as attempts to use the deaths of public figures and private citizens to advance political narratives.
It said such actions amounted to taking advantage of grieving families for political gain.
“This is unacceptable,” the DCI said.

The agency maintained that investigations would not be conducted through the media and that sensitive operational information would not be released where doing so could jeopardise ongoing inquiries.
Where investigations establish criminal culpability, the DCI said suspects would be processed according to the law and presented before the appropriate authorities.
Gachagua urged to submit evidence
The DCI specifically addressed members of the public, including Gachagua, who may have information concerning alleged criminal activity.
It urged them to submit such information through official investigative channels.
The agency said credible information would be assessed and acted upon in accordance with the law.
The Directorate reaffirmed its commitment to working with the Independent Policing Oversight Authority (IPOA), the Office of the Director of Public Prosecutions (ODPP), the Judiciary and other constitutionally mandated institutions.
It said its investigations would continue to be guided by professionalism, impartiality, integrity, human rights and the rule of law.
The DCI statement was signed by J. K. Marete, HSC, for the Director of Criminal Investigations, and dated August 11, 2026.
