The Office of the Special Prosecutor (OSP) has revealed a pivotal role in the United States Federal Bureau of Investigation (FBI)’s successful conviction of former Tema Oil Refinery (TOR) Managing Director, Asante Kwaku Berko, in a complex bribery case originating from Ghana. This development underscores a significant level of international cooperation in combating cross-border corruption, particularly within the realm of energy-related illicit activities. The OSP stated that its assistance was integral to the prosecution, acknowledging a substantial contribution from the United States Department of Justice (DoJ) as ‘significant assistance to this prosecution’ in the case.
For the past several weeks, the OSP has been meticulously providing investigative and evidentiary support to the FBI, acknowledging that this collaboration has been crucial to the pursuit of justice. The OSP’s involvement was initially described as ‘behind-the-scenes’ and extended beyond simple support, emphasizing its strategic contribution to the investigation’s progress. The OSP detailed that the relationship began with Ghana’s established mutual legal assistance framework, a cornerstone of the legal system designed to facilitate cooperation between jurisdictions.
The case centers around a purported bribery scheme involving Asante Kwaku Berko and several Ghanaian officials, dating back between 2014 and 2015. The alleged scheme involved payments exceeding US$1 million intended to influence the development and financing of a power plant in Ghana, a project linked to a Turkish energy company, Aksa Enerji Uretim A.S. This project was a client of US-based investment bank Goldman Sachs, further complicating the situation and highlighting the transnational nature of the illicit dealings.
The OSP’s statement revealed that a significant portion of its collaboration with the FBI took place through Ghanaian authorities, providing investigative and evidentiary support as the FBI relentlessly pursued the case. The OSP highlighted the importance of this international cooperation in addressing corruption within the energy sector, emphasizing that it serves as a vital component of law enforcement efforts across borders. The case demonstrates how the United States Department of Justice, through its involvement with the OSP, has been actively working to prosecute individuals involved in this type of illicit activity, reinforcing the importance of such collaborative efforts.
The outcome of the trial – a conviction on August 6, 2026 – has resulted in a maximum prison sentence of 30 years for Berko. The OSP has scheduled a sentencing hearing on November 10, 2026, and the legal team is working to ensure full transparency and accountability in the proceedings. The OSP is emphasizing the significance of the international partnership, stating that it ‘underscores the vital role of collaborative efforts in combating cross-border corruption’ and that the case highlights the importance of mutual legal assistance arrangements within the context of international law enforcement.
The OSP’s official notice indicates that the investigation was initially initiated by the FBI, and the extent of the OSP’s contribution has been carefully documented and validated by the DoJ. This collaboration extends beyond mere support; the OSP’s involvement has been recognized as a significant factor in the prosecution of this complex case, demonstrating the dedication of international partners in bringing about justice and deterring future illicit activity.
