The National Treasury has appointed 3 internal auditors to conduct a fresh audit at the Health ministry.
However, the revelations have ignited fears of a cover-up of the alleged possible fraud of Sh3.2 billion.
The three auditors reported to the ministry on Thursday last week, with reports that the National Intelligence Service (NIS) has also been collecting evidence at Afya House.
The sources said Bernard Muchere, the internal auditor and a certified fraud examiner who blew the whistle on the suspected fraud, has been left out in the fresh audit.
“We have so far been able to establish that all expenditures under the audit report have been accounted for,” said Mailu via the star, despite the public storm.
The CS had announced he would constitute an independent probe by a private firm, but some MPs warned him he would shoulder the cost.
The National Assembly and the Senate are also investigating the matter.
