The Cyber Security Authority (CSA) has arrested and secured the remand of Aderinsola Oluwanifemi Adeleye, a Nigerian national. This arrest follows an intelligence-led investigation into alleged cyber-enabled financial crimes involving compromised United States banking cards.
This case began on June 25, 2026, after a report from Haatso Shell Filling Station management. They reported suspicious Point of Sale (POS) transactions flagged by Ecobank Ghana. The transactions were linked to two Citi Bank debit cards issued in the United States.
Such financial crimes could damage Ghana's reputation as a safe hub for international business and investment. They highlight the growing need for robust cyber security measures in the digital economy. The incident also points to potential vulnerabilities in Ghana's payment systems and the challenges of cross-border financial crime.
A brief provided to Graphic Online confirmed the operation's collaboration with the Ghana Police Service. International partners, including INTERPOL and the FBI, also assisted in the investigation. The suspect admitted using a debit card for transactions at fuel stations. He claimed an individual in the United States sent it to him with a balance of about US$10,000. He also stated he had used approximately US$8,000, equivalent to GHS 96,000 at an exchange rate of GHS 12 to 1 US dollar.
Investigators allege that fuel station POS systems processed fake fuel purchases. Cash was allegedly collected in place of actual fuel. The CSA stated that accomplices linked to this scheme are still being pursued. This ongoing investigation will determine the full extent of the fraudulent activities and identify all involved parties.
The transactions were traced to POS terminals at fuel stations in Haatso and Osu. Internal investigations identified two pump attendants suspected of involvement. These attendants were arrested and allegedly led investigators to the main suspect. The suspect was later arrested at Haatso Shell Filling Station during a return visit. Authorities found him with a Citi Bank VISA debit card and a Beretta pistol loaded with live ammunition.
Further searches at his office in Katamanso and residence in Oyarifa recovered additional ammunition, mobile phones, and other electronic devices. Forensic examination of these devices will provide more evidence. The CSA's swift action in this case demonstrates Ghana's commitment to combating cybercrime. It also shows its dedication to protecting its financial infrastructure from international fraud. This event underscores the importance of continued vigilance and collaboration among local and international law enforcement agencies. These efforts are crucial to safeguarding the integrity of financial transactions and consumer trust.
