The Republic has closed its case against former National Signals Bureau (NSB) Director-General Kwabena Adu-Boahene, his wife Angela Adjei Boateng and their company, Advantage Solutions Limited, over the alleged theft of GH¢49.1 million.

Deputy Attorney-General Dr Justice Srem-Sai, in a Facebook post explaining the day’s proceedings, outlined how the prosecution’s case unfolded before the court on Tuesday, September 8, 2026.

Step 1: The State’s case

According to Dr Srem-Sai, the Republic’s allegation is that Adu-Boahene used what prosecutors describe as “clever means” to move GH¢49.1 million belonging to a State agency into a private company’s bank account, with the alleged assistance of his wife and their company.

The three accused persons face charges including stealing, money laundering and causing financial loss to the Republic. They have pleaded not guilty.

Step 2: Four witnesses called

The prosecution called four witnesses before closing its case.

The first was the family driver of Adu-Boahene and his wife, who testified that he ran money errands for the couple and transported large sums of money from banks to them, as well as their friends, family and associates.

The second witness, the Head of Finance of the affected State agency, testified about the agency’s financial procedures and the process for purchasing cybersecurity defence systems.

Dr Srem-Sai said the witness told the court that the names on three cheques did not correspond with the account into which the money was eventually deposited.

The witness also stated that no such defence system had been ordered by the agency and that the invoice number cited by Adu-Boahene belonged to completely different equipment purchased by the agency on another occasion.

Step 3: Following the money

The third witness, an employee who handled the personal financial and business affairs of Adu-Boahene and his wife, testified about how the money was allegedly spent through their company and other entities, families and associates.

The witness also gave evidence concerning the accused’s dealings with banks, investments and payments to builders working on landed properties.

Step 4: EOCO evidence

The fourth and final witness was EOCO investigator Frank Marshall Cromwell, whose cross-examination was completed before the Republic closed its case.

He tendered the three cheques and deposit slips, company incorporation and bank documents, account statements, property purchase records and documents relating to Adu-Boahene’s salary, companies and assets.

The court has given the accused persons until September 25, 2026, to file submissions of no case to answer. The Republic will have 14 days to respond after being served.

The case has been adjourned to November 5, 2026.
