The substance of a case being built by the Office of the Special Prosecutor (OSP) against former Chief Executive of the National Petroleum Authority (NPA), Mustapha Abdul-Hamid, has been put to question following the circulation of a document outlining witnesses the prosecution intends to subpoena.
The document, dated January 12, 2026, and issued from the Office of the Special Prosecutor at South Ridge, Accra, lists a series of exhibits and names of individuals described as witnesses the prosecution plans to compel to testify. The witnesses include chief executives and senior managers of several oil marketing and energy companies operating in Ghana.
The OSP is expected to ask the court to compel these individuals to testify that they were extorted by Mustapha Hamid during his tenure at the NPA.
The document details multiple exhibits, including investigation and charge cautioned statements from individuals such as Isaac Mensah, Bright Bediako-Mensah, Kweku Aboagye Acquaah, Wendy Newman and others, all dated between April and May 2025. It further lists at least 13 witnesses the prosecution intends to subpoena, drawn largely from the petroleum downstream sector.
The OSP has not yet publicly outlined the full scope of its case or responded to the criticism circulating online. Similarly, Mustapha Abdul-Hamid has not issued a fresh public statement in response to the emergence of the subpoena list.
The case forms part of ongoing high-profile anti-corruption proceedings by the OSP, which have continued to attract public debate, particularly over prosecutorial strategy, evidentiary thresholds and the use of compelled testimony.
