An anti-corruption court sitting in Eldoret also issued a warrant of arrest for another accused person, who has not appeared before court over the same accusations.
Simam and her husband recently presented themselves before the court in Eldoret after a warrant of arrest was issued against them.
The warrant then was issued after they failed to honour summons to appear before the Ethics and Anti Corruption Commission (EACC) office in Eldoret to shed light on alleged tender scam.
Simam, her husband, Enock Kimeli and three others were charged with conspiracy to commit economic crimes. They have denied committing the offence.
The court had also ordered that they have their fingerprints taken. Thursday, Principal Magistrate Dolphina Alego also issued a warrant of arrest for another suspect, Wisedom Kimutai Maina who is still at large despite the initial warrant.
He had been expected to take plea of the charges but has never shown up. So far, five accused persons have taken plea to the charges and are out on bond awaiting the mention of the case on July 4. It will be heard on July 20.
The charges stated that the offence was committed between January 6 and April 1, 2010, in Eldoret, Uasin Gishu County.
The accused allegedly conspired to commit an offence by influencing the award of contract No UG/2-27-09/10-003 for routine maintenance and spot improvement of Bayete-Chuiyat-Bargeiywa road in Eldoret South.
The contract was awarded to Kachur Holdings Ltd, a company that did not qualify for such an award according to the public procurement and disposal Act No 3 of 2006 because one of its directors was a public servant.
