Former Interior CS Fred Matiang'i has left the DCI headquarters after over six hours of grilling.
The former CS was accompanied by a bevy of lawyers led by Danstan Omari for the questioning session.
He arrived at 8 am for the grilling over the alleged police raid at his Karen home on the night of February 8 which police insist never happened.
Police said they found Matiang'i answerable to two charges relating to the alleged raid.
The first charge is conspiracy to commit a felony contrary to Section 317 of the Penal Code and publication of false information contrary to Section 23 of the Computer Misuse and Cybercrimes Act.
"I caution you that you are not obliged to say anything unless you wish to do so but whatever you say, shall be taken down inwriting and might be given as evidence in court," Chief Inspector Maurice Shiraho told the former CS.
Omari said after the grilling that the date for arraignment was not disclosed by the officers.
"They said they are not taking waziri (Minister) to court today. So what then remains is that it is a date they will present the charge sheet before the court and we shall present Waziri before that court," he said.
