In an interview with Citizen TV on Tuesday night, Mr Ouko revealed that after his retirement from the sensitive office, his security was withdrawn and that he is yet to receive some allowances owed to him and which were due by the time he left office.
During his tenure, Mr Ouko unearthed many scandals, looting of public coffers and wastage of public funds in the county governments, national government ministries and departments, agencies and semi-autonomous agencies.
Mr Ouko, a man whose name many government officers came to fear, revealed that there have been no security arrangements for him after he left office.
Mr Ouko has now urged parliament to establish a legal framework to ensure the Auditor-General is safe even after leaving office.
Mr Ouko has previously admitted that his office was a roller-coaster that saw him receive threats on his life, especially during his tenure, but he said that relevant State investigative agencies swiftly took action.
