Six Nigerian nationals are set to face charges in the United States over an alleged $6 million online romance scam.
The men were arrested in Cape Town, South Africa, in 2021.
South African police said they would be handed over to US authorities and transported to the United States.
They are expected to face wire fraud and money laundering charges.
Nigerians accused in $6m romance scam
Authorities accuse the six men of belonging to an organised criminal network.
According to Africanews, South African police say the group allegedly targeted more than 100 women in the United States.
The alleged victims included pensioners and businesspeople.
Investigators say the suspects built online relationships with victims before allegedly obtaining money from them.
Authorities estimate that more than $6 million was lost.
However, the allegations have not yet been proven in court.
Suspects to be handed over to US authorities
South African police said the six men would be transferred from a correctional facility in Cape Town.
They were then expected to be taken to Cape Town International Airport.
There, officials from the FBI and US Secret Service were due to receive them.
The suspects are expected to face legal proceedings in the United States.
Authorities link suspects to Black Axe network
Authorities allege that the men are connected to a network known as Black Axe.
Interpol has linked the network to cyber-enabled financial crime.
Such crimes can include romance, cryptocurrency and investment scams.
However, the six men will face charges based on the specific allegations against them.
Interpol targets online fraud networks
The case comes as international authorities increase efforts against online financial fraud.
Last month, an Interpol operation targeting West African organised crime groups led to 58 arrests.
Authorities also identified 263 suspects linked to different criminal networks.
The operation focused on money laundering and online fraud.
Meanwhile, authorities in South Africa raided seven locations in Johannesburg during a separate operation.
Interpol said police arrested 39 people.
Authorities also seized $2.67 million and froze more than 250 bank accounts.
The operation targeted an alleged network accused of running romance and investment scams.
International authorities continue to investigate similar online fraud networks operating across borders.
