Nigeria’s computer software expert Sapphire Egemasi risks 20 years imprisonment in the United States (US) if she is found guilty of alleged multimillion-dollar cyber fraud
A Nigerian software programmer commonly addressed as ‘Tech Queen’, Sapphire Egemasi has been arrested in the United States (US) over an alleged cyber-related crime involving about $1.3 million. Her arrest followed a federal grand jury indictment filed in 2024, which charged her and several co-conspirators with internet fraud and money laundering.
Egemasi is facing up to 20 years in federal prison after being arrested by the Federal Bureau of Investigation (FBI) over her alleged involvement in a transnational fraud syndicate that defrauded multiple U.S. government agencies of millions of dollars.
Known for flaunting a luxurious lifestyle on social media and boasting affiliations with top tech firms, she was apprehended around April 10, 2025, in the Bronx, New York city.
The crime, based on reports, took place between September 2021 and February 2023.
Available court documents prove that Egemasi was a key player in a sophisticated cybercrime operation allegedly led by a Ghanaian national identified as Samuel Kwadwo Osei.
The group targeted US municipal institutions, including the city government of Kentucky, using phishing schemes and spoofed websites to steal login credentials and reroute public funds to fraudulent accounts.
Egemasi’s specific role was to leverage her programming skills to design fake websites mimicking those of legitimate US government agencies.
These sites tricked employees into providing secure login information, which the syndicate used to access accounts and siphon off funds. Investigators said that Egemasi was also instrumental in laundering the stolen money, helping to move it through various banks via wire transfers.
One court filing detailed how the group successfully redirected $965,000 from the city of Kentucky to a PNC Bank account under their control in August 2022.
In another instance, $330,000 was transferred to an account with Bank of America. The fraudulent transfers were masked to appear legitimate, further complicating detection by financial institutions.
Federal prosecutors believe Egemasi resided in Cambridge, United Kingdom, before her arrest and previously spent time in Ghana, where she reportedly met her co-conspirators. She then became the syndicate’s primary tech specialist, responsible for executing the technical components of the fraud from overseas.
To conceal the origins of her wealth, Egemasi falsely claimed to have interned at multinational corporations such as British Petroleum (BP), H&M, and Zara. These claims, aimed at bolstering her credibility and deflecting suspicion, were unsupported by evidence, according to investigators.
On platforms like LinkedIn and Instagram, Egemasi cultivated a strong personal brand as a successful tech entrepreneur.
She frequently shared images of designer fashion, tech gadgets, and international travel to destinations including Greece, Portugal, and France. Her carefully curated persona earned her admiration among aspiring African tech professionals, many of whom saw her as a role model for digital success.
However, the FBI’s investigation has revealed a stark contrast between Egemasi’s online image and her alleged criminal activities. Authorities say her luxurious lifestyle was funded almost entirely by proceeds of crime, obtained through the exploitation of vulnerabilities in government financial systems.
Egemasi and her co-defendants, including other Ghanaian nationals, are now in federal custody and awaiting trial in Lexington, Kentucky. Each of them faces up to 20 years in prison if convicted, alongside substantial monetary fines and the possibility of deportation after serving their sentences.
