Treasury Cabinet Secretary (CS) Henry Rotich was on Tuesday morning grilled by the Directorate of Criminal Investigations (DCI) over corruption allegations.
Reports indicate that the CS was questioned over the multi-billion scandal surrounding the construction of Arror and Kimwarer dams.
Intense grilling
Rotich reported at the DCI headquarters at around 6am and he had not left the premises by 9am.
This is the second time that the CS is appearing before the DCI having previously recorded a statement with the DCI over the matter.
More than Ksh20 billion was reportedly paid out although construction works at the site was yet to commence.
Corrupt CSs
On Monday, reports emerged indicating that at least four CSs were using proxy companies to fraud the government.
This emerged after a team led by the Director of Public Prosecutions Noordin Haji visited Italy where they unearthed details on how firms directly linked to the CSs were winning Government contracts.
