Former Director-General of the National Signals Bureau, Kwabena Adu-Boahene, has suffered another setback in his ongoing trial over the alleged misappropriation of GH¢49.1 million in a cybersecurity software deal.

During proceedings on April 20, 2026, the defence attempted to introduce a SWIFT transfer receipt linked to his private company, Advantage Solutions, suggesting it originated from the NSB.

The document was intended to form the basis for questioning the prosecution’s second witness, Ruby Edith Adumuah.

However, the prosecution, led by the Deputy Attorney General, objected, arguing that the witness had no personal knowledge of the document and that it was irrelevant to the case.

The defence countered that the witness, as Head of Finance, was competent to speak on such financial records, having identified the document as a SWIFT transfer receipt.

Presiding judge, Justice Francis Achibonga, ruled in favour of the prosecution, sustaining the objection.

The court held that the witness’s lack of direct knowledge—highlighted by her use of the word “seem” in describing the document—undermined its evidential value.

The ruling marks a significant moment in the trial, as the court continues to scrutinise the admissibility and credibility of documents presented by both sides in the high-profile case.
