ACCRA, Ghana — Ghanaian authorities have arrested and charged Nigerian national Aderinsola Oluwanifemi Adeleye in connection with an alleged transnational financial fraud investigation involving compromised United States-issued bank cards.

According to Ghana’s Cyber Security Authority (CSA), the investigation involved the Ghana Police Service and international law-enforcement partners, including the International Criminal Police Organization (INTERPOL) and the United States Federal Bureau of Investigation (FBI). Authorities said Adeleye had become a person of significant investigative interest in connection with suspected cyber-enabled financial crimes.

The investigation reportedly began on June 25, 2026, after a complaint concerning suspicious Point-of-Sale (POS) transactions at a fuel station in Accra. The transactions allegedly involved two U.S.-issued Citibank debit cards and were subsequently traced to POS terminals at fuel stations in Haatso and Osu. (csa.gov.gh)

Investigators allege that the scheme involved fraudulent POS transactions in which compromised bank cards were used to obtain transaction approvals. Instead of legitimate fuel purchases, authorities say cash was allegedly provided following the transactions.

The investigation reportedly resulted in the arrest of two fuel-station attendants who investigators believe may have assisted in processing the transactions. According to authorities, the attendants identified Adeleye and another individual as people allegedly connected to repeated suspicious transactions.

Police subsequently arrested Adeleye after he allegedly returned to one of the filling stations to conduct another transaction, according to the CSA’s account.

Investigation Expands

Following the arrest, investigators reportedly recovered a U.S.-issued debit card allegedly connected to the investigation. Authorities also reported recovering a firearm and ammunition during searches associated with the case.

A court-approved search of premises linked to Adeleye reportedly resulted in the seizure of electronic devices, including mobile phones, which investigators have retained for forensic analysis. Authorities say the examination is intended to determine the extent of the alleged financial operation and identify possible additional participants.

Investigators also allege that Adeleye admitted using one of the recovered bank cards at fuel stations. Authorities said he claimed the card had been provided by an acquaintance in the United States and that approximately US$10,000 was associated with the card, with about US$8,000 allegedly spent or withdrawn before his arrest.

Possible Proceeds of Crime Under Investigation

The investigation has also expanded beyond individual transactions. Authorities are reportedly examining assets allegedly connected to the suspect, including a house, a cement-block manufacturing business, a pickup vehicle and other properties.

The CSA said investigators are working to determine whether any of those assets were acquired with proceeds from the alleged financial crimes.

The investigation also involves examining possible international connections and identifying other individuals who may have participated in the alleged network.

Case Remains Before the Courts

The case highlights the increasingly international nature of financial and cyber-enabled crime, where compromised payment cards can be used across borders and investigations can require cooperation between domestic law-enforcement agencies and international organizations.

However, Aderinsola Oluwanifemi Adeleye has not been convicted of the allegations described above. The charges remain matters for the Ghanaian courts, and he is presumed innocent unless proven guilty.

Authorities say investigations remain ongoing as they work to establish the full scope of the alleged operation, trace suspected proceeds of crime and determine whether additional suspects are involved.
