The Ethics and Anti-Corruption Commission has intensified investigations into Nyamira County after summoning Governor Amos Nyaribo over allegations of corruption and economic crimes estimated at about Ksh.400 million.
The governor appeared before investigators at the EACC’s Nairobi Integrity Centre, where he was interviewed and recorded a statement regarding the claims. The case centres on the construction of the Nyamira County government offices, a project that has now drawn serious scrutiny from the anti-graft agency.
According to EACC, the main focus of the probe is an alleged irregular procurement process that led to the award of a Ksh.382 million contract to Spentech Engineering Limited.
Investigators believe the process may not have followed the law and that payments made to the contractor may not match the actual work done on the site.
The commission says the company was allegedly paid amounts that exceeded the value of work completed, raising concerns about possible loss of public funds.
Beyond the construction contract, EACC is also examining claims that Governor Nyaribo irregularly authorised payments to himself amounting to Ksh.18 million.
These payments were allegedly disguised as ex gratia payments and reimbursements for house allowance. Investigators are trying to establish whether these payments were lawful, approved through proper channels, or whether they were meant to conceal personal benefits drawn from county resources.
The governor was summoned through a formal letter sent to his lawyers earlier this month.
The letter confirmed that EACC had agreed to reschedule the interview at the request of the governor’s legal team. It stated that the interview and statement recording would take place on December 17, 2025, at 10:00 am at the Nairobi Integrity Centre. The appearance followed this arrangement, marking a key step in the ongoing investigation.
These developments come after earlier search operations carried out by EACC on October 28, 2025. The searches were conducted in Nyamira, Kisii, and Nairobi counties and targeted homes and offices of several county officials who have been identified as persons of interest.
During these operations, investigators sought to recover documents and digital material that could help establish how decisions were made, how payments were approved, and whether procurement laws were followed.
EACC has also named several other county officials who are under investigation in connection with the matter. They include Lameck Machuki Nyariki, the Director of Housing and Physical Planning, Peris Mose, the Director of Roads who previously served as Head of Procurement, Asberth Maobe, the Chief Officer for Finance and Accounting Services, and Josphat Oruru, the Chief Officer for Roads, Transport and Public Works. Investigators are examining their roles in procurement, payment approvals, and project supervision.
The commission has stated that these investigations are part of broader efforts to determine the full extent of alleged corruption and economic crimes within the Nyamira County government.
EACC says the findings will help establish responsibility, assess any loss of public funds, and guide possible next steps under the law.
