A Prosecution witness in the ongoing trial of the Former Director of the National Signals Bureau, Kwabena Adu Boahene appears to have corroborated portions of a 7th May 2025 memo from the lawyers of Kwabena Adu Boahene to the National Security Coordinator detailing operational expenditure of monies he and two others are being accused of allegedly misappropriating. 

The Prosecution witness, Edith Ruby Opokua Adumuah who also doubles as the Director of Finance at the National Signals Bureau, in a witness statement dated the 2nd of June 2025, mentioned that she was indeed the custodian of all the cheque books of the bank accounts held by the Bureau.

She further revealed that before any cheque payment was made on the main account, a request was made by the recipient unit through the head of Administration, who then forwarded the request to the Director of BNC for approval after the necessary documents had been attached before certification by the internal Audit unit for authorization of payment.  

Ms Opokua Adumuah also revealed that the operational account of the BNC by standard procedure is managed by the Director of BNC (Kwabena Adu Boahene) with the able supervision of the National Security Coordinator. 

Paragraph 8 of Ms Opokua Adumuah’s statement  mentions that before a cheque was signed on the operational account, Kwabena Adu Boahene would always inform her either verbally or through a phone call before cheques are written. She would then forward it to both Mr Adu Boahene for his signature and that of the National Security coordinator Joshua Kyeremeh. 

In paragraph 14, witness Edith Ruby Opokua Adumuah confirms that payments were indeed made to the Israeli Company ISC Holdings Limited which delivered the cyber defense system for the National Signals Bureau. 

“I know of ISC Holdings Limited. A1 (Kwabena Adu Boahene) gave me an invoice of Seven Million United States dollars (US$7,000,000.00) to transfer funds to ISC Holdings Limited. The invoice was dated September 1, 2020. BNC commenced paying for this invoice on October 15, 2020.”

“We made payment to ISC Holding on the invoice from BNC's "The Director BNC" accountant at Fidelity Bank. I know that BNC paid as much as Three million and One hundred and ten thousand united states dollars (3,110,000.00) in respect of this invoice. I have copies of the invoice and the payments. I wish to tender them in evidence (INDEX EROA1). This transaction is from the transaction in respect of which A1, A2, A3 and A4 are being tried.” 

Her testimony brings to question the state’s claim that expenditure from the operational account of the National Signals Bureau, which is often clothed in secrecy, but subject to prior approval from the National Security Coordinator impugns wrongdoing on Mr Adu Boahene and his wife.  

It will be recalled that on May 7, a leaked memo from Adu Boahen detailed how some finances of the NSB were disbursed. 

The document showed that GH₵8.3 million was disbursed in September 2024 to provide an unnamed opposition party with communications equipment for election collation, justified as ensuring "Stability of Nation/National Cohesion/Political Impartiality."

 The letter further indicated that GH₵960,000 was paid to the Defence and Interior Committee in 2020/2021 as "allowances" for enacting the National Signals Bureau Act, with an additional GH₵309,000 going to the Subsidiary Legislation Committee in 2024.

Election-related expenditures totaled over GH₵14 million, including GH₵7.2 million for the December 2020 polls and GHS 6.7 million for the December 2024 elections.

The documents also show GHs5.1 million was spent on luxury vehicles (2024 Nissan Patrols and a Land Cruiser) for a "Special Aide to the President-Elect" in December 2024.
