The Ethics and Anti-Corruption Commission has launched investigations into a Sh30 million insurance tender in Nyamira county.
Sources at the EACC offices in Kisumu and Nyamira county assemblies said the investigations began on Thursday.
"The EACC investigators demanded all documents relating to the tender. They asked for minutes of the evaluation committee, tender board and bids from other insurance companies," said a source at the county assembly yesterday.
The source added: "They sought whether the laid down procedures were adhered to. They asked for the advertisement and whether the insurer was paid."
Johncele Insurance Brokers Ltd was awarded the tender on March 25.
It was paid on April 4 before the MCAs gave their details.
Yesterday, it emerged that there were two evaluation committee and two tender committee reports.
"One report advised against Johncelle Insurance brokers and one which supported it. They have to establish who doctored the minutes," added another source.
Nyamira Senator Mong'are Okong'o said those implicated should step aside for investigations.
"The tender committee and the Public Service Board members should step aside until investigations are concluded," added Okong'o.
He added: "The writing is on the wall. The investigations will extend to the executive."
Following the tender, Nyamira assembly speaker Peter King'oina was impeached and Majority leader Beauttah Omanga replaced.
Deputy Speaker Andrew Magangi said all the people adversely mentioned in the scandal will be interdicted.
