Police units around the world have joined forces in a series of covert operations targeting one of West Africa’s most feared criminal networks – Black Axe. Interpol called the operation a “major blow” to the Nigerian crime network, but warned that its international reach and technological sophistication mean it remains a global threat.

In one notorious example, Canadian authorities said they had busted a money-laundering scheme linked to Black Axe worth more than $5bn (£3.8bn) in 2017.  “Black Axe and similar groups are responsible for the majority of the world’s cyber-enabled financial fraud as well as many other serious crimes”.
