A man accused of masquerading as a powerful State House insider to extort millions from a senior government official has been arraigned before the Milimani Anti-Corruption Court in Nairobi.
Omosira Osumo on Monday pleaded not guilty before Senior Principal Magistrate Hon. C. A. Okore to three criminal counts, including personating a public officer and bribery.
According to the charge sheet, Mr. Osumo is accused of falsely presenting himself as the Chief of Staff and Head of Public Service, Mr. Felix Koskei, in an elaborate scheme to defraud Engineer Kenneth Njuguna Mbogori, a Regional Director at the Kenya Rural Roads Authority (KeRRA).
The court heard that on January 14 and 15, 2026, within Nairobi County, the accused allegedly demanded a staggering Ksh. 10 million from Engineer Mbogori, claiming he would “protect” his lucrative position at KeRRA. Prosecutors told the court that Mr. Osumo, a private citizen, had no authority whatsoever to make such representations.
In one of the bribery counts, the prosecution stated that on January 14, 2026, Mr. Osumo unlawfully requested a financial advantage of Ksh. 10 million from the engineer. The following day, he allegedly received Ksh. 30,000 from the complainant, money prosecutors say was part of the same fraudulent plan to influence the engineer’s job security.
Principal Prosecution Counsel Mr. Willy Momanyi urged the court to impose strict bond terms, citing the seriousness of the charges and the risk of interference with evidence. He asked the court to compel the accused to surrender his passport, provide a contact surety, and seek court permission before travelling outside the court’s jurisdiction.
The prosecution also requested two weeks to furnish the defence with documentary exhibits and witness statements. Additionally, they opposed the release of two mobile phones confiscated from the accused, arguing they are key exhibits in the case.
“I am satisfied with the explanations given by the prosecution counsel on the issues regarding confiscation of the mobile phones belonging to the accused person,” ruled Hon. Okore.
In her determination, the magistrate granted Mr. Osumo release on a bond of Ksh. 1 million or an alternative cash bail of Ksh. 300,000. She further ordered him to surrender his passport and all travel documents to the court pending the hearing and determination of the case.
The matter is scheduled for mention after two weeks as investigators finalize the evidence in what prosecutors describe as a brazen attempt to exploit the influence of high public office for personal gain.
