A Nigerian tech enthusiast known online as the “tech queen,” Sapphire Egemasi, has been arrested by the Federal Bureau of Investigation (FBI) in connection with a massive fraud scheme targeting U.S. government agencies.
Egemasi, a programmer with an active Devpost profile, was apprehended around April 10, 2025, in the Bronx, New York, reports The Nation.
She was arrested alongside several alleged co-conspirators, including Ghanaian national Samuel Kwadwo Osei, believed to be the ringleader of the syndicate.
The arrests follow a federal grand jury indictment filed in 2024, which charged the group with multiple counts of internet fraud and money laundering. The crimes allegedly took place between September 2021 and February 2023.
According to prosecutors, the syndicate defrauded the city of Kentucky of millions of dollars by creating spoof websites that mimicked official U.S. government portals. These fraudulent platforms were used to harvest login credentials and redirect funds into accounts under the group’s control.
Investigators say Egemasi served as the technical lead of the operation. She allegedly designed the fake websites and managed the coordination of wire transfers.
Records show that in August 2022 alone, the group rerouted $965,000 into a PNC Bank account and funneled another $330,000 into a Bank of America account.
Before her arrest, Egemasi was reportedly based in Cambridge, United Kingdom, though authorities believe she previously lived in Ghana, where she may have forged ties with other members of the syndicate.
To mask the origin of her wealth, Egemasi claimed on social media and professional platforms to have held internships with multinational corporations such as British Petroleum, H&M, and Zara.
Her LinkedIn profile portrayed a polished image of a successful tech professional, while her social media accounts featured images of lavish vacations to destinations like Greece and Portugal —trips prosecutors allege were funded by illicit gains.
Egemasi and her co-defendants are currently in federal custody, awaiting trial in Lexington, Kentucky. If convicted, each faces up to 20 years in prison, hefty financial penalties, and likely deportation upon completing their sentences.
