The single sharpest fact in one or two punchy sentences. Who did what, where, when, and why it matters. Not a summary of everything — the one thing that makes someone stop scrolling. A reader who only reads this paragraph must understand what happened. The Economic and Financial Crimes Commission (EFCC) has charged Ahmed Adamu Dikko, the immediate past managing director of Port Harcourt Refining Company (PHRC), and Jimoh Olasunkanmi Yisawu, his counterpart at Warri Refining and Petrochemical Company (WRPC), with money laundering over the alleged diversion of funds earmarked for the rehabilitation of Nigeria's refineries. The anti-graft agency filed the charges before the High Court of the Federal Capital Territory (FCT), Abuja, on June 22nd. The charges are the latest development in the EFCC's investigation into the multi-billion-naira turnaround maintenance programme for Nigeria's refineries, which has so far led to the recovery of billions of naira, millions of dollars, and several properties from former officials of the Nigerian National Petroleum Company Limited (NNPCL). Ahmed Adamu Dikko, who was appointed managing director of PHRC in 2022, allegedly engaged in multiple transactions involving proceeds of unlawful activities linked to contractors handling refinery maintenance projects. According to court documents, one of the counts alleged that in February 2024, while serving as managing director of PHRC, Dikko made a cash payment equivalent to N218.375 million to purchase a property located at Plot 558, Abubakar Umar Street, Katampe Extension, Abuja, without passing through a financial institution, contrary to the Money Laundering Act. The EFCC also accused Dikko of retaining N100 million allegedly received from Ebenco Global Link Limited, a contractor to PHRC, in a Fidelity Bank account between October 2022 and October 2023, knowing the funds were proceeds of unlawful activity. In separate counts, prosecutors alleged that Dikko retained N90 million allegedly paid by Ebenco Global Link Limited through a GTBank account; concealed the origin of another N90 million by routing the funds through an Access Bank account belonging to Aisha Ahmed Dikko; received N30 million through the account of Medinus Mildred Oluba from Ebenco Enterprises, another contractor; Additionally, the persecutors accused Dikko to have retained N10 million allegedly paid by Dogai Global Resources, also a refinery contractor and also retained N4.75 million received from Gasontex Limited. The commission further alleged that Dikko and Masterpiece Projects & Investment Limited concealed the source of N328.71 million paid by OMSA Integrated Services Limited from transactions involving NNPC's allocation of Vacuum Gas Oil for export. Other counts alleged that he received N59.2 million from funds transferred to Masterpiece Projects & Investment Limited; procured Ebenezar Oluwagbemiga of Ebenco Global Link Limited to receive N356.41 million on his behalf, converted $77,080 through Ibrahim Isa Yaro between October 2022 and May 2025 and received N20 million through a GTBank account operated by his son, Ahmed Ahmed Dikko. Jimoh Olasunkanmi Yisawu: The former managing director of WRPC was also charged with eight counts of money laundering, including operating an account used to conceal illicit funds and making large cash transactions in violation of the Money Laundering Act. Yisawu allegedly laundered proceeds of unlawful activities and received payments from contractors engaged by NNPCL. Ahmed Adamu Dikko and Jimoh Olasunkanmi Yisawu both allegedly engaged in multiple transactions involving proceeds of unlawful activities linked to contractors handling refinery maintenance projects. The investigation into the multi-billion-naira turnaround maintenance programme for Nigeria's refineries has so far led to the recovery of billions of naira, millions of dollars, and several properties from former officials of NNPCL.
