Evidence gathered in the United States could help the Office of the Special Prosecutor (OSP) in its investigation. This is according to private legal practitioner Martin Kpebu.
The investigation involves Asante Kweku Berko, a former banker at Goldman Sachs and former boss of the Tema Oil Refinery. He is linked to a bribery case.
Kpebu stated that evidence tested in the US could make the OSP's case stronger. This follows recent developments in the probe.
The OSP is looking into the Ghanaian aspects of the bribery allegations against Berko.
The Special Prosecutor has been leading efforts to uncover the full extent of the alleged bribery.
Further details on the nature of the US evidence were not immediately available.
