Law enforcement agencies have arrested some 800 suspected criminals around the world after thousands of people were tricked into using an encrypted phone app which allowed police to monitor their conversations without their knowledge.
Australian police have told local media that the man who unwittingly helped to distribute the FBI-run encrypted messaging app was a fugitive named Hakan Ayik.
Alleged to be a drugs kingpin himself, officials say Mr Ayik was identified as a key influencer and given access by undercover agents to a handset which he then recommended to other criminal associates.
