A husband and wife, alongside another accomplice have been charged at the Kibera Law Courts over a fraudulent scheme that led to the misappropriation of more than Sh22 million from the National Oil Corporation of Kenya (NOCK).
Detectives from the Investigations Bureau (IB) attached to the Ministry of Energy and Petroleum, arraigned the three on Thursday, following investigations into allegations of theft and misappropriation of public funds lodged by the State-owned corporation.
According to the investigators, Gladys Kahaki Njubi, a former Assistant Accountant at the National Oil Corporation, was the mastermind behind these fraudulent activities.
She conspired with her husband Griffin Nyakang’o Omwenga, and a third accomplice, Nehemiah Onyunge Kibegwa, leading to the misappropriation of millions of shillings before resigning from her position.
Detectives further found out that Omwenga had registered five companies including Zoccon Enterprises Limited, Eceny Ventures Limited, Earthcare Supplier Services, Sparktec Ventures Limited, and Jaffer Petrofill Africa Limited. The companies allegedly received close to Sh22 million in payments despite never bidding for or providing services to NOCK.
Njubi allegedly used genuine documents belonging to legitimate companies that had contracts with NOCK to conceal the scheme.
She did that to ensure that her husband’s companies were not detected during the payment approval process. Being an assistant payable accountant, Njubi was directly involved in processing the fraudulent transactions.
The third suspect, Kibegwa, a director of Kensons Construction Limited, is also accused of benefitting from this elaborate scheme, after his company received millions of shillings despite having no prior bidding or engagement with the National Oil Corporation.
Upon completion of the investigation, the case was forwarded to the Office of the Director of Public Prosecutions (ODPP), which approved the charges, including conspiracy to defraud, theft by servant, forgery, and possession of proceeds of crime, among other offences.
In a swift response, the three suspects were arrested on January 28, 2026, and detained at Akila Police Station. In court, they pleaded not guilty to the charges and were remanded pending a bond ruling which was scheduled for 4th February, 2026.
According to the authorities, this case highlights the commitment put in place by the DCI to curb corruption, enforcing accountability, and safeguarding public resources by ensuring all offenders face justice.
