Former Director-General of the National Signals Bureau (NSB), Kwabena Adu Boahene, and his wife, Angela Adjei Boateng, have pleaded not guilty to all charges in a corruption case involving alleged fraudulent contracts worth GHS 49 million, equivalent to approximately $7 million.

They appeared in court alongside businesswoman Mildred Donkor and Advantage Solutions Limited to face an 11-count indictment comprising charges such as stealing, defrauding by false pretences, money laundering, and wilfully causing financial loss to the state.

During the High Court proceedings, all accused persons denied the allegations after the charges were read out. Mr Adu Boahene specifically entered a plea of “Not guilty” to three counts of stealing public funds.

He and his wife also rejected claims of conspiring to steal from the state. On charges related to fraud and financial loss to the state through a cybersecurity contract allegedly involving Israeli company ISC Holdings Limited, the former NSB boss again denied any wrongdoing.

He further pleaded “Not guilty” to using his public office for private gain. His wife, Angela, also denied aiding in any corrupt acts. Mr Adu Boahene maintained his innocence on a charge of obtaining property by false pretences.

Prosecutors say that from 2020 to 2023, Adu Boahene misappropriated GHS 49 million by pretending to acquire cyber defence software for national use—systems that, investigations later revealed, were never delivered to Ghana’s security institutions.

Court filings allege that Angela, in her capacity as a director at Advantage Solutions Limited, collaborated in laundering the stolen funds. Mildred Donkor, a former bank official linked to the case, has also been charged for allegedly facilitating suspicious transactions.

It was further disclosed that BNC, a private company established by Mr Adu-Boahene and his wife while he was still in office, was used as a vehicle to process transactions tied to the alleged cybersecurity contract with ISC Holdings Limited. While GHS 9.5 million (roughly $1.75 million) was initially paid to ISC Holdings, authorities say subsequent funds were diverted for personal gain, including investments and untraceable transfers.

According to court documents, the three main accused are said to have operated a sophisticated scheme through Advantage Solutions Limited, which acted as a holding company. The funds reportedly ended up being laundered through subsidiaries like BNC and used for diverse business ventures such as treasury bill investments, real estate, fertiliser manufacturing, and luxury car rentals.

Adu Boahene was arrested on March 20 at Kotoka International Airport after returning from abroad but was later granted bail.

In a related development, Mr Adu Boahene and his wife have filed a defamation lawsuit against Attorney General and Minister of Justice Dr Dominic Ayine. The couple claims that statements made by Dr Ayine during a March 24, 2025, press conference falsely painted them as criminals and money launderers, harming their reputations and subjecting their children to public ridicule and bullying.

Their lawsuit details several concerns, including what they describe as premature public branding as criminals, dissemination of false claims about their finances and travel history, and the alleged exposure of sensitive national security issues. They argue that the Attorney General’s statements were malicious and intended to destroy their credibility.

As part of their legal action, the plaintiffs are seeking punitive and exemplary damages, a permanent injunction to prevent further defamatory comments, and full legal costs, including attorney fees.
