Justice James Omotosho of the Federal High Court in Abuja has convicted former Minister of Power Saleh Mamman on a 12-count charge bordering on fraud and money laundering.
The charges were filed by the Economic and Financial Crimes Commission (EFCC).
Delivering judgment, Justice Omotosho ruled that the anti-graft agency successfully proved the case against the former minister beyond reasonable doubt.
Mamman, who served under former President Muhammadu Buhari, was found guilty of illegally diverting public funds amounting to about ₦33.8 billion.
The court also held that he made a cash payment of $655,700, equivalent to about ₦200 million, for the purchase of a property in Abuja without using a financial institution, contrary to financial regulations.
The former minister was arrested in 2021, months after he was removed from office by former President Buhari.
During the trial, the EFCC presented 17 witnesses and tendered 43 exhibits in support of its case.
According to the commission, Mamman conspired with ministry officials to divert approximately ₦22 billion meant for the Zungeru Hydroelectric Power Project and Mambilla Hydroelectric Power Project projects.
Investigators also alleged that part of the diverted funds was used to acquire luxury assets both within and outside Nigeria.
The court fixed May 13, 2026, for sentencing.
