Kenya's Directorate of Criminal Investigations (DCI) is probing a Ksh4 billion emergency fuel deal that led to the arrest of former senior energy officials and is investigating a local tycoon-owned firm and a Swiss oil company.

• The investigation centers on an irregular Ksh4 billion emergency cargo purchase.
• Key figures arrested include former EPRA Director General Daniel Kiptoo, former KPC MD Joe Sang, and former Petroleum PS Mohamed Liban.
• Officials allegedly manipulated fuel stock data to trigger the purchase of substandard fuel at inflated prices, bypassing established procedures.
