The International Criminal Police Organisation (INTERPOL) has arrested two suspects in Nigeria during separate investigations into cybercrime, including an international investment fraud scheme linked to more than $2.4million in suspected criminal proceeds.
The arrests were disclosed in a statement on Operation Serengeti III, an international cybercrime enforcement operation conducted between June 29 and August 31, 2026, with law enforcement agencies from 21 countries participating.
According to the statement published on INTERPOL’s website, Nigerian authorities arrested one suspect linked to a large-scale phishing and business email compromise operation that harvested software credentials and amassed approximately 2.1 million email addresses.
Investigators also recovered a luxury vehicle suspected to have been purchased with proceeds from criminal activities.
In a separate investigation, Nigerian authorities arrested another suspect over an international investment fraud scheme allegedly promoted through messaging applications.
Financial investigations linked the scheme to the movement of more than $2.4million in suspected criminal proceeds, much of which was allegedly laundered through cryptocurrency transactions.
The names of the two suspects were not disclosed in the statement.
INTERPOL said Operation Serengeti III targeted cyber-enabled fraud, ransomware, business email compromise, online scams and digital extortion.
The operation involved law enforcement agencies from 21 countries, resulting in the arrest of 1,462 suspects, the disruption of 10,909 malicious networks and the recovery of more than $105m in illicit funds.
Authorities also identified 65,929 victims targeted by cybercriminal networks, while financial investigations linked criminal activities to losses exceeding $385million.
The operation received support from private-sector partners, who provided intelligence, technical analysis and operational expertise to help investigators identify suspects, map criminal networks and advance investigations.
INTERPOL’s Director of Cybercrime, Neal Jetton, said cybercrime networks exploited technology to target victims across national borders.
“Operation Serengeti III reinforces a clear message: while cybercrime is increasingly borderless, international cooperation remains one of the most effective tools for disrupting criminal networks, recovering criminal assets and protecting communities from digital harm,” he said.
INTERPOL added that several investigations arising from the operation remained active, with authorities continuing efforts to identify additional suspects, trace illicit proceeds and analyse seized digital evidence.
Nigeria participated in the operation alongside Angola, Benin, Cameroon, Congo, Côte d’Ivoire, the Democratic Republic of the Congo, Eswatini, Gabon, The Gambia, Ghana, Kenya, Mozambique, Rwanda, Senegal, South Africa, Tanzania, Uganda, the United States, Zambia and Zimbabwe.
