Lawyer Donald Kipkorir now says Deputy President Rigathi Gachagua has a plan to restrain the mandates of the Directorate of Criminal Investigations (DCI).
Taking to his Twitter handle on Thursday, Kipkorir said DCI was Constitutionally mandated to stop crimes before they are committed.
"Role of DCI is to investigate crime already committed and disrupt crime before it is committed … Penal Code has both sets of crime: But our Deputy President wants the DCI not to prevent crime," he said.
He was weighing in on remarks made earlier on Thursday by Gachagua during a governor's induction in Mombasa.
Gachagua told the Directorate to keep off government offices while pursuing crime suspects.
"We have told DCI to go back to Kiambu road (DCI Headquarters) and wait for crimes to be reported there," he said.
"They have no business in government offices, hovering all over has created a toxic environment for service delivery."
Gachagua also said junior officers should not be sent to interrogate sitting leaders, saying it is disrespectful.
"Let the head of that particular organisation write a letter to the governor himself and not delegate to some junior officers to address a sitting governor. That is not right."
DCI roles include detecting and preventing crimes and undertaking investigations on serious crimes including homicides, narcotics, money laundering and economic crimes.
Others include collecting and providing criminal intelligence, apprehending offenders, maintaining criminal records, coordinating country Interpol Affairs and carrying out investigations of matters that may be referred to it by the Independent Police Oversight Authority.
