Former Kasarani MP Elizabeth Ongoro is in South Africa for medical treatment, her representatives told the court on Monday.
Mrs Ongoro, who served as nominated Senator in the last parliament, is among 21 people being sought by EACC over embezzlement of Sh48 million.
At the court, the representatives told Chief Magistrate Lawrence Mugambi that the former legislator is in South Africa for treatment, although they did not give further details.
Eight people took plea on Monday over the loss of Sh48 million that was meant for construction of Kasarani Girls High School between 2008-13.
They are Silvan Thomas, Pamela Achola, Jecinta Akoth, Nashon Okumu, Kefa Omanga, Douglas Ntaine, Peter Otingo and Vitalis Ogingo Obunga.
"You are not allowed to visit Kasarani constituency offices from today due to ongoing investigations," Mugambi told those who were charged.
"Those who did not appear have until Friday to present themselves to Ethics and Anti-Corruption offices," Mugambi added.
Also being sought by the sleuths is Mrs Ongoro's husband Ferdinand Masha. He did not also present himself to the court as ordered by the police.
Ongoro, who served as an assistant minister during 10th parliament, is the eldest sister to Rarieda MP Otiende Amollo, an accomplished lawyer.
