The Directorate of Criminal Investigations (DCI) has quizzed the Kenya National Trading Corporation (KNTC) boss Pamela Mutua over the Sh16.5 billion edible oils scandal.
DCI also grilled several top officials at the KNTC and they are currently being questioned at the DCI Headquarters along Kiambu Road, Nairobi.
Sources have told The Standard that Mutua was the first to be questioned over the oil importation saga.
It is reported that also grilled were managers of a bank that guaranteed the business after Ethics and Anti-Corruption Commissions officials commenced the investigations a few months ago.
The scandal came to the limelight after MPs from the National Assembly's Agriculture Committee raised concern over the duty-free import and how the suppliers were identified.
