The prosecution has closed its case in the trial of former National Signals Bureau Director-General Kwabena Adu-Boahene, his wife Angela Adjei-Boateng and their company.
Deputy Attorney-General and Minister for Justice Dr Justice Srem-Sai announced on Tuesday, September 8, 2026, after State Attorneys and EOCO investigators called four witnesses to support allegations that the couple stole and laundered GH¢49.1 million belonging to a state agency.
Dr Srem-Sai laid out the prosecution’s case in a detailed statement, describing the central allegation as straightforward: that Adu-Boahene used deceptive means to divert the funds, with his wife and their company assisting in spending the money, resulting in charges of stealing, money laundering and causing financial loss to the Republic.
Dr Srem-Sai said Adu-Boahene’s primary answer to the allegations is that he did not spend the money on himself, his family or friends, but used it instead to purchase a cyber defence system for the state agency he led. That claim forms the core of the defence the trial will ultimately need to test once the accused persons open their case.
Four Witnesses, One Financial Trail
The prosecution built its case through four witnesses, each contributing a different piece of the alleged money trail. The first witness, described as A1 and A2’s family driver, testified to running money errands for the couple, including carrying large sums from banks to Adu-Boahene, his wife, and their friends, family, and associates.
The second witness, the Head of Finance at the state agency whose money Adu-Boahene is accused of stealing, testified to the agency’s procurement and financial processes. Dr Srem-Sai said this witness established several critical facts:
That the names on three cheques did not match the bank account into which Adu-Boahene deposited them, that no cyber defence system had ever been ordered by the agency, that the invoice number Adu-Boahene claimed to have used for the purchase actually belonged to entirely different equipment the agency had bought on a separate occasion, and that the bank account receiving the three cheques was not the agency’s account at all, with the agency confirming it had no knowledge of the company or its account.
The third witness, an employee who handled Adu-Boahene and Adjei-Boateng’s personal financial and business affairs, testified to how the couple spent the money through their company and other entities, families and associates.
Dr Srem-Sai said this witness explained how a bank filed a suspicious transaction report over Adu-Boahene’s account activity, forcing him to close the account, and testified to investments in real estate and financial instruments.
The witness tendered pre-signed cheques from the couple, some of which were traced to payments made to builders working on properties in Accra and Asokore Mampong.
The EOCO Investigator’s Evidence
The fourth witness, an EOCO investigator, brought documentary evidence into the record.
This included the three cheques and deposit slips allegedly used to move the GH¢49.1 million from the state agency’s account into Adu-Boahene’s private company account, incorporation and bank account opening documents for the couple’s companies, and bank statements tracing how the money was spent after the transfer.
It also includes purchase receipts and property documents linking real estate acquisitions to Adu-Boahene’s private accounts, and a record of his salary as a civil servant over roughly two decades set against the companies and assets he came to own.
With the prosecution’s case now closed, the court has given the accused persons until September 25, 2026, to file a submission of no case to answer, a legal motion arguing that the evidence presented does not establish a case requiring a defence.
The Republic will have 14 days to respond once served with that submission. The matter has been adjourned to November 5, 2026, when the court is expected to rule on the submission or determine next steps in the proceedings.
A Case Built on Financial Reconstruction
Dr Srem-Sai’s account presents a prosecution case constructed almost entirely around documentary and testimonial reconstruction of a financial trail, from the original cheques through the receiving company’s bank account to the property purchases the funds allegedly financed.
Whether that evidentiary chain survives the defence’s submission of no case to answer, and whether Adu-Boahene’s account of a cyber defence system purchase withstands scrutiny against the state agency’s own procurement records, will shape how the case proceeds toward its November hearing date.
