The prosecution of Kwabena Adu-Boahene, the former Director-General of the National Signals Bureau (NSB), his wife Angela Adjei-Boateng, their associate Mildred Donkor, and their jointly owned company, Advantage Solutions Limited, is intensifying as three key witnesses have provided testimonies in court.
The four are currently standing trial for multiple counts, including stealing, causing financial loss to the state, and conspiracy, related to the alleged diversion of GH¢49.1 million in public funds.
At the heart of the case is the alleged diversion of GH¢49,100,000.00 from the Bureau of National Communications (BNC), the predecessor to NSB, under the guise of purchasing a cyber defence system that investigators say was never delivered.
Below is a summary of the witness statements, as sighted by 3News.com, made by lead investigator Frank Marshall Cromwell; NSB Director of Finance, Edith Ruby Opokua Adumua; and Frank Anane Dekpey, who identified himself as an errand assistant to the accused persons.
EOCO investigator exposes elaborate scheme
Frank Marshall Cromwell, an investigator and Staff Officer at the Economic and Organised Crime Office (EOCO), provided a detailed account of the alleged financial malfeasance.
He testified that the investigation, initiated in March 2025 following a tip-off, revealed that Mr. Adu-Boahene (A1) signed an international contract in January 2020 for a US$7 million cyber defence system with an Israeli company, ISC Holdings Limited.
EOCO’s probe established that A1 diverted the equivalent amount in Ghana cedis (GH¢49.1 million) from the BNC’s Fidelity Bank account into a private company account named “BNC Communications Bureau Limited – Operations” at UMB Bank.
Cromwell detailed how this UMB account was opened just one day before the first of three cheques, totaling GH¢49.1 million, was deposited, suggesting it was created solely for the diversion. He stated that only a fraction (US$1.75 million) was actually transferred to ISC Holdings, after which A1 embarked on a “spending spree” with substantial cash withdrawals for personal use, often facilitated by A3.
The investigator also revealed that other companies linked to the accused showed no legitimate business operations, and significant properties allegedly acquired with these funds have been frozen by court order.
Finance Director details protocol exploitation
Edith Ruby Opokua Adumuah, the Director of Finance at NSB, corroborated the mechanics of the transfers.
She testified that as the custodian of BNC’s cheque books, she was instructed by A1 to write cheques for large sums, with the payee ambiguously described as “BNC Operations”.
Due to a “need-to-know” security policy within the Bureau, she complied with A1’s instructions, believing these were legitimate BNC operational accounts, unaware they belonged to a private company owned by A1 and A2.
Ms. Adumuah recounted that former Director-General Kwabena Adu-Boahene (A1) directly instructed her to write three large cheques, totaling GH¢49.1 million, payable to “BNC Operations.” Trusting these were legitimate, yet undisclosed, BNC operational accounts, she complied and deposited the funds into a UMB account as directed by A1.
Ms. Adumuah also highlighted that reasons for payments from operational accounts were never disclosed to her, and she noted A1’s specific reliance on A3 for bank errands, even after A3 had left UMB Bank.
Errand boy reveals cash movements
Frank Anane Dekpey, who served as an errand boy for A1, A2, and A3, provided crucial insight into the physical handling of the illicit funds.
He testified that A3 frequently sent him to withdraw and deposit large sums of money from UMB and Stanbic banks, often transported in “big Ghana Must Go bags”.
Dekpey stated that he would typically deliver these large cash withdrawals to A1’s office. He also confirmed making deposits into the Stanbic Bank account of “Vertex Solutions,” a company previously identified by the EOCO investigator as being linked to the accused persons.
