DCI officers arrested the suspect along Garissa Road in Thika on Thursday evening and took him to Wang'uru Police Station for interrogation.
The arrest came two days after Mr Ndambiri asked police to arrest the suspect to shed light on the case involving a pilot e-learning project at Karoti Girls’ Secondary School, Mwea Constituency.
On Tuesday, Mr Ndambiri dismissed the allegations against him as falsehoods, saying his political enemies from the region had embarked on a smear campaign to tarnish his name.
A man accused of falsely linking Kirinyaga Deputy Governor Peter Ndambiri to the alleged theft of Sh138 million for e-learning has been arrested.
Offices from the Directorate of Criminal Investigations (DCI) arrested the man along Garissa Road in Thika on Thursday evening and took him to Wang'uru Police Station for interrogation.
