The Economic and Financial Crimes Commission (EFCC) has constituted an investigative team to probe individuals named in alleged questionable transactions linked to the Mambilla Hydroelectric Power Project, following a recent International Chamber of Commerce (ICC) tribunal ruling in favour of Nigeria.

According to Premium Times, sources familiar with the development disclosed that the team is being supervised by EFCC Chairman, Ola Olukoyede. The investigation is expected to focus on payments and financial transactions highlighted in the tribunal’s findings, which reportedly raised concerns over the involvement of individuals linked to the controversial power project.

The probe follows the ICC tribunal’s dismissal of major claims brought by Sunrise Power and Transmission Company Limited against Nigeria over the 3,960-megawatt Mambilla project in Taraba State. The company had sought $680 million as a settlement sum and interest in connection with a separate arbitration claim exceeding $2.7 billion. The tribunal also ordered Sunrise and its promoter, Leno Adesanya, to refund Nigeria’s $11.8 million in legal fees and rejected a claim seeking $400 million in settlement payments.

Among those mentioned in the tribunal’s findings are former Vice President Atiku Abubakar, his former wife Jennifer Douglas, former Attorney-General of the Federation Abubakar Malami, ex-Power Minister Olu Agunloye, former National Security Adviser Sambo Dasuki, his son Abubakar Dasuki, Abdullahi Yola and Dere Awosika. Sources told Premium Times that the EFCC may invite Atiku and Douglas for questioning. The tribunal examined a $500,000 payment made by Adesanya to Douglas’s US bank account in January 2003, but said the explanation that it was linked to a foreign-exchange transaction for Atiku was not supported by documentary evidence. Atiku has denied being indicted by the tribunal and said he was not responsible for awarding the contract.

The tribunal also raised concerns over other payments, including $1.74 million received by Abubakar Dasuki, which he reportedly described as a loan but failed to substantiate to the panel’s satisfaction. Malami and Agunloye are already facing separate EFCC trials connected to alleged financial misconduct and the Mambilla project, respectively. The latest investigation is expected to examine the transactions and individuals identified in the ICC proceedings, although the EFCC has not publicly confirmed the reported invitations. The allegations remain subject to investigation and due process.
