A Nairobi-based civil society organization has called for the immediate suspension and investigation of four Nairobi City County revenue officers over allegations of corruption, abuse of office, and revenue leakage involving public service vehicle (PSV) operators and seasonal parking revenue.
In a demand letter dated September 30, 2026, the Civil Society Reference Group (CSRG) accused the officers of allegedly facilitating the under-billing of PSV fleets operating within Nairobi’s Central Business District (CBD) and other commercial centres, leading to substantial revenue losses for the county government.
According to the letter addressed to Nairobi County Secretary Dr. Machel Waikenda, the officers are alleged to have deliberately failed to capture the correct number of vehicles within fleet accounts, billing only a fraction of the vehicles while allegedly receiving illegal payments for the unrecorded units.
The organization claimed that the alleged scheme has resulted in significant revenue leakage and may have involved manipulation of the county’s revenue management systems.
“The above-named officers be immediately suspended from their duties pending investigations; their access rights and privileges to all County revenue management systems be suspended forthwith to safeguard evidence and prevent interference with investigations; an independent and comprehensive investigation be undertaken into the allegations of corruption, abuse of office, revenue leakage and system manipulation; and appropriate disciplinary, civil or criminal action be initiated against any persons found culpable,” the letter states.
CSRG further alleged that similar irregularities have been occurring in the issuance and renewal of seasonal parking tickets for private vehicles, resulting in additional loss of county revenue.
The organization contends that the officers may have interfered with the county’s revenue management system by failing to accurately record vehicle details, thereby concealing the actual amount of revenue due to the county government.
The officers named in the complaint are Deputy Director of Operations Paul Wanga, Systems Officer Emmanuel Chanzo, PSV Section In-Charge Fiona Kimani, and staff member Jane Njoki.
CSRG has demanded the immediate suspension of the four officers pending investigations and the withdrawal of their access rights to all county revenue management systems to preserve evidence and prevent possible interference with investigations.
The group has given the county administration 48 hours to respond to its demands, warning that it may pursue legal action and other lawful accountability measures if no action is taken.
