The Office of the Director of Public Prosecutions (ODPP) has closed an inquiry into allegations relating to KUPPET National Treasurer Mwethi Njenga's use of different names in official records, saying the evidence did not meet the threshold for criminal prosecution.
The decision followed a review of an inquiry file submitted by the Directorate of Criminal Investigations (DCI) after former Bomet Central MP and former KUPPET Assistant National Treasurer Ronald Tonui raised concerns over Njenga's use of different names in official records.
Tonui had alleged that Njenga used different names on his national identity card, degree certificate and Teachers Service Commission (TSC) records, and questioned the authenticity of some of the documents.
In a letter dated June 12, 2026, the ODPP said it had reviewed the evidence contained in the duplicate inquiry file and found that the allegations did not meet the threshold required to sustain criminal charges.
"The evidence in the police duplicate does not meet the threshold required of a prosecutable case with a realistic and reasonable prospect of a conviction against the suspect," Deputy Director of Public Prosecutions Robert Oyimbo said.
"We therefore direct that this file be closed with no further police action. The police duplicate file is herewith returned."
The complaint arose from allegations that Njenga had used different variations of his name at different stages of his life and career.
According to the ODPP's review, investigations established that he was born on November 5, 1962, to Robert Njenga Mwethi and Nellie Njoki Munyinyi and was baptised on June 1, 1974, under the name Wicks Mwethi.
His birth certificate recorded him as Wicks Leonard Njenga, while school records showed that he sat his CPE examination in 1976 as Njenga Mwithi before joining Kirangari High School, where he sat his KCE examination in 1980 as Leonard Mwethi.
In 1983, he sat his Form Six examinations and was registered as Leonard Njenga Mwithi.
The ODPP's review further found that Njenga later obtained a national identity card bearing the name Wicks Mwethi Njenga.
According to university records cited by the ODPP, he joined Kenyatta University to pursue a Bachelor of Education (Arts) and graduated on December 8, 1988, with Second Class Honours (Lower Division) under the name Leonard Njenga Mwethi.
The Kenya Revenue Authority confirmed that his Personal Identification Number (PIN) was registered under the name Wicks Mwethi Njenga.
TSC records showed that he joined the commission in May 1988 as Mwethi Leonard Njenga. A January 2026 confirmation from the commission identified him as Wicks Leonard Njenga Mwethi, TSC number 273299, and stated that he had been in active service between May 23, 1988, and September 2004.
The ODPP also noted that Kimani Kahete & Co Advocates and Commissioners for Oaths confirmed that an affidavit of attestation of names sworn on April 11, 2018, was executed in their presence by a person identified as Wicks Mwethi Njenga, using the same identity card number cited in the investigation.
The ODPP said its decision on whether to charge a suspect is guided by factors including the relevance, admissibility, reliability, credibility and availability of evidence, as well as the strength of rebuttal evidence and public interest.
After reviewing the records, the ODPP concluded that the discrepancies in the names appearing in various documents did not establish a prosecutable criminal case against Njenga.
The decision brings to a close the DCI inquiry arising from Tonui's complaint.
