A Nigerian behind an online fraud network which engineered scams worth more than $60m has been arrested in Port Harcourt in a joint operation by Interpol and the Economic and Financial Crimes Commission.
"The 40-year-old Nigerian national, known as 'Mike', is believed to be behind scams totalling more than $60 million involving hundreds of victims worldwide," the international police organisation said in a statement.
"In one case, a target was conned into paying out $15.4m," Interpol said.
"The network compromised email accounts of small to medium businesses around the world including in Australia, Canada, India, Malaysia, Romania, South Africa, Thailand and the United States," it said.
The suspect ran a network of at least 40 people working from Nigeria, Malaysia and South Africa which used malware and carried out the fraud, and he also had money laundering contacts in China, Europe and the US who provided bank account details for the illicit cash flow.
"Following his arrest in Port Harcourt in southern Nigeria, a forensic examination of devices seized by the EFCC showed he had been involved in a range of criminal activities including business e-mail compromise and romance scams," it said.
The suspect and a fellow fraudster, 38, who was also arrested in the city, face charges including hacking, conspiracy and obtaining money under false pretences.
