Transparency International Ghana Executive Director Mary Addah has urged Ghanaian authorities to question all individuals linked to the case involving former Goldman Sachs banker Asante Kwaku Berko as part of efforts to uncover the full details of the alleged corruption.
Mrs Addah said Ghana must not limit its response to the conviction secured against Mr Berko in the United States but should thoroughly examine the Ghanaian side of the case.
She argued that investigating the roles of all persons mentioned in connection with the alleged bribery scheme would help establish the facts, identify any wrongdoing and determine whether public officials or private individuals violated Ghanaian laws or ethical standards.
According to her, a comprehensive investigation would also enable the country to draw important lessons from the case and strengthen measures to prevent similar incidents in the future.
Mrs Addah made the comments on Joy FM’s Super Morning Show on Monday, August 10, 2026, while discussing the bribery case involving Mr Berko and a power project in Ghana.
“Apart from saying we are cancelling (the) contract, we must also be interrogating all the people who were mentioned. And again, I believe that as people who are willing and ready to fight corruption, this is a good opportunity to show that what happened in the past can be brought back to day and be dealt with,” she said.
Her call follows Mr Berko’s conviction in the United States over his alleged involvement in a bribery scheme connected to the development of a power project in Ghana.
The conviction has renewed public interest in the circumstances surrounding the project and the possible involvement of other individuals.
Mrs Addah maintained that authorities should use the development as an opportunity to conduct a thorough investigation rather than treating the US conviction as the end of the matter.
She said establishing the respective roles of everyone connected to the case would be crucial to determining whether any Ghanaian officials or other actors engaged in conduct that breached the law.
The call comes as the Attorney-General’s Office has indicated that Ghanaian authorities are working with their counterparts in the United States to investigate the Ghanaian dimension of the case.
Mrs Addah said the ongoing developments provide Ghana with an opportunity to demonstrate its commitment to fighting corruption by ensuring that anyone found to have participated in wrongdoing is held accountable, regardless of their position or status.
