Detectives from the Directorate of Criminal Investigations (DCI) have arrested the former Sports Cabinet Secretary Rashid Echesa.
Sources aware of the arrest say the former CS is being held over suspected fraud.
Echesa has been taken to the DCI Headquarters along Kiambu Road.
His vehicles were also impounded during the Thursday arrest.
Echesa was fired by president Uhuru Kenyatta from the sports docket in March 2019.
