Directorate of Criminal Investigations detectives grilled Treasury CS Henry Rotich for Sh20 billion payments made to firms linked to Kimwarer and Arror dams. He was released by 4:30 PM, 11 hours after he checked himself in at the DCI headquarters.

It is not clear whether his fingerprints have been taken by the DCI.

In the past, no Cabinet Secretary has ever spent more than 10 hours under interrogation and failed to take a plea for the offence for which he/she was summoned. At best, such top ranking officers are only left off the hook as state Witnesses.

Rotich has to answer 300 questions posed by hard nosed DCI officers.
