A “sophisticated internet fraud syndicate” has been uncovered in Zambia, leading to the arrest of 77 people, including 22 Chinese nationals.

It was a “significant breakthrough in the fight against cybercrime”, the authorities said after a multi-agency raid on a Chinese-run company.

The firm employed Zambians who believed they were to be call-centre agents.

Among equipment seized were devices allowing callers to disguise their location and thousands of Sim cards.
