The Office of the Special Prosecutor (OSP) has summoned the Commissioner-General of the Ghana Revenue Authority (GRA), Anthony Sarpong; the Assistant Commissioner for Finance, Celestine Annan; and the Technical Assistant to the Commissioner-General, Kenneth Agyei-Duah, to appear before investigators in connection with the ongoing probe into the controversial GRA–Strategic Mobilisation Ghana Limited (SML) revenue assurance contract.
This development follows the arrest of Freeman Sarbah, Acting Head of Legal Affairs at the GRA, on Monday, November 3, 2025, for alleged involvement in corruption and obstruction of justice related to the same deal.
Sources at the OSP confirmed that the three senior officials were summoned after it emerged they allegedly instructed the Acting Head of Legal to issue a letter to SML’s lawyers in mid-October — a directive investigators believe may have significant implications for the ongoing investigation.
It is the second time both Mr. Sarpong and Ms. Annan have been invited by the OSP. According to insiders, their earlier statements reportedly conflict with the contents of the letter they are accused of approving or authoring.
Both Mr. Sarpong and Mr. Agyei-Duah previously worked with KPMG, the auditing firm that reviewed SML Ghana’s operations under former President Nana Addo Dankwa Akufo-Addo’s directive earlier this year.
In a statement released via its official channels on Monday, the OSP confirmed that Mr. Sarbah is under investigation for suspected corruption, obstruction of justice, and other corruption-related offences connected to the SML contract.
The controversial GRA–SML agreement, which engaged SML Ghana to provide revenue assurance services in Ghana’s downstream petroleum sector and other industries, has been under intense scrutiny following allegations of inflated costs, procurement breaches, and questionable terms.
Following widespread public concern, the OSP launched a full-scale investigation to uncover possible conflicts of interest, abuse of office, and violations of procurement laws. The probe has since widened to include several top officials at the GRA and the Ministry of Finance.
Special Prosecutor Kissi Agyebeng has hinted that prosecutions are expected to begin before the end of November 2025. Those likely to face charges include former Finance Minister Ken Ofori-Atta, ex-GRA Commissioners-General Dr. Ammishaddai Owusu-Amoah and Emmanuel Kofi Nti, and other high-ranking officials and advisors.
Preliminary OSP findings reportedly reveal evidence of corruption, abuse of office, and serious procurement violations in the award and execution of the SML contracts — initially intended to enhance government revenue collection.
The OSP has reaffirmed its commitment to ensuring accountability and protecting public funds, warning that all individuals found culpable will face full legal consequences.
