Deputy President William Ruto is yet to formally lodge a complaint with the DCI following claims of an alleged assassination attempt.
According to sources within the investigation, DP Ruto will only record his statement with DCI boss George Kinoti.
DCI Head of Economic Crime Unit Michael Sang had been assigned the duty on Monday but he did not succeed to meet Dr Ruto at his office despite pitching camp there for hours.
"He was kept waiting for the better part of Monday afternoon in vain. We are still waiting for the way forward," an unnamed source told Standard.
Conventionally, the DCI boss does not carry out menial duties at the investigators unit which could explain why he had delegated the duty to his junior.
Parties within the DCI headquarters suspect that the DP might use the opportunity to confront the investigations boss over how he is running matters as he has done in the past.

Mr Kinoti on Tuesday confirmed that it was the DP who made a phone call to report the alleged assassination plot.
The investigations boss further outlined that the letter that was circulated on social media is their primary focus for noe.
"We are treating that letter seriously and investigators want to ascertain its authenticity. Once we know the source of the letter and how it came to existence, we shall focus on the authenticity of the issues raised," he noted.
