A Chief Inspector, Kiptoo Kisoroi, has told the Milimani Anti-Corruption Court that Webtribe, also known as JamboPay, Director Danson Muchemi tried to lure former Nairobi County Governor Mike Mbuvi Sonko to work with him.

The JamboPay director is said to have attempted several times to bribe the then County boss in a bid to secure a lucrative revenue collection tender.

Kisoroi, who is currently the Sub-County Police Commander in Hulugho, Garissa County, further told the court that the information came from an audio recording that the former County boss managed to capture when Muchemi visited his Kanamai residence.

Appearing before Principal Magistrate Charles Ondieki on Wednesday, July 16, 2025, he also told the court that Muchemi confessed to Sonko that the first Nairobi County Governor, Evans Kidero, had benefited from the same deal.

According to Kisoroi, the JamboPay director revealed to the then Nairobi County Governor that Kidero had pocketed Ksh7 billion from the deal during his five-year tenure.

“What was interesting to me was that Muchemi was telling the Governor that if he agreed to work with him, he would earn Ksh4–5 million a day. He also told him that the previous Nairobi Governor, Evans Kidero, had made Ksh7 billion from the same deal he was offering him,” Chief Inspector Kisoroi told the court.

The Chief Inspector also narrated to the court that on January 1, 2019, while stationed at the Directorate of Criminal Investigations (DCI) Mtwapa as a Police Constable, the Deputy DCIO called him to his office where he met the former Governor.

The DCIO then briefed him that the Governor was seeking their assistance in recording the incriminating bribery conversation between him and Muchemi, who had visited him at his Kanamai residence in Kilifi County.

After the briefing, Kisoroi told the court that he booked an OB 35/10/01/2019 at the Mtwapa Police Station and proceeded to issue Sonko with a Sony ICD-PX 470 audio recorder (serial number 1161788) to secretly capture their conversation.

They also showed him how to use the device and hid themselves in another room during the meeting.

He informed the court that he had brought a CD on which the recording was captured, and stated that the audio lasted 57 minutes and 16 seconds. He then sought permission to play the audio as part of his evidence.

“We believe the audio evidence will further shed light on the depth of corruption in the revenue collection tender,” Kisoroi told the court.

However, Magistrate Ondieki adjourned the proceedings to Thursday, July 17, 2025, at 9:30 am, when the recording will be played in open court.
