The Office of the Special Prosecutor (OSP) has identified five people as persons of interest in its investigation into the Ghanaian dimension of the bribery case involving former Goldman Sachs banker and Tema Oil Refinery Managing Director, Asante Kwaku Berko.
The five are former Power Minister Kwabena Donkor; Francis Walkson Kwasi Dzafa, a former Technical Adviser to the Minister of Power; Solomon Adjetey Sowah, a Deputy Director; Lyndon Nii Mettle, Director of Tricorp Group Limited; and Baffour Ankomah Brobbey, an employee of Tricorp Group Limited.
Special Prosecutor Kissi Agyebeng stressed that being named a person of interest does not mean any of the five is a suspect or has been found culpable of an offence.
The OSP’s announcement follows Berko’s conviction by a federal jury in Brooklyn, New York, on 6 August 2026, over his involvement in a bribery scheme involving more than US$1 million in payments to Ghanaian officials in connection with the development and financing of a power plant.
The project involved Turkish energy company Aksa Enerji and the Government of Ghana.
US prosecutors established that Berko and his associates discussed and made payments intended to influence Ghanaian officials and secure government approvals for the power project.
The scheme, according to evidence presented during the US proceedings, operated between 2014 and 2015, when Ghana was experiencing severe power shortages.
Court evidence also referred to a proposed payment of US$1 million to the then Minister of Power, who was responsible for key approvals needed to advance the project.
Other payments allegedly involved Ghanaian officials and persons connected to the Ministry of Power, as well as expenses associated with a trip by Ghanaian officials to Turkey to inspect equipment for the proposed plant.
Some of the Ghanaian officials referenced in the US proceedings were not publicly identified and were instead described using labels including “Ghana Official 1” and “Ghana Official 2.”
The OSP said its involvement in the matter did not end with providing assistance to US investigators.
Kissi Agyebeng said the office had continued investigating the Ghanaian dimension of the case and would pursue the matter based on evidence obtained through its own investigations.
The identification of the five persons of interest therefore marks a further step in the OSP’s efforts to establish whether offences were committed in Ghana in connection with the power project.
The OSP has not indicated that the five persons have been charged with any offence.
