Devolution Cabinet Secretary Eugene Wamalwa on Thursday took to Twitter to divulge details of his engagement with the Directorate of Criminal Investigations (DCI) investigators.
The CS had been summoned to record a statement to assist with the probe into the Sh21 billion Arror and Kimwarer dams scandal.
CS Wamalwa was quick to note that he was not interrogated as a culprit, adding that he was not involved with the projects in any way.
"Today I recorded a statement DCI on Arror/Kimwarer dams probe where I clarified that they were not under my jurisdiction.
"Urged Kenyans to support the ongoing investigations and the fight against corruption by our agencies," he tweeted.
CS Kiunjuri grilled by DCI
Agriculture CS Mwangi Kiunjuri had also been summoned by the DCI for the same investigation.
Unlike his Devolution counterpart, CS Kiunjuri did not inform the public on the goings on at the DCI.
Treasury CS Henry Rotich made headlines last week after he was grilled by the DCI for three consecutive days.
Commenting on the investigations, DCI boss George Kinoti explained that the most suspicious bit of the transactions was the hurry to award tenders to CMC di Ravenna.
"This is a complex investigation and we want to hear from all those who were involved to understand why there was a rush to award the contract.
"We want to understand why the officials were in a hurry to award these tenders and lift the lid on this theft,"the DCI boss stated.
