Alleged pedophile extradited from NZ

A New Zealand man allegedly involved in a worldwide pedophile ring which abused the adopted son of a gay Cairns couple will be extradited to Australia to face charges.

The 42-year-old was arrested in August 2016 following a five-and-a-half year investigation.

Police announced on Thursday he would be extradited to Brisbane to face nine charges of indecent treatment of a child under the age of 12.

Queenslanders Peter Truong and Mark Newton were jailed for 30 and 40 years respectively in the United States in 2013 after they admitted buying the boy as a newborn from Russia and abusing him.

They recorded the assaults on high-definition video cameras and shared the footage with a worldwide pedophile ring.

He was then passed around through the network to be abused by other men.

Police identified the 42-year-old New Zealand man during examinations of the chat logs, images and videos on Truong and Newton's electronic devices.

It showed he had allegedly sexually abused the child and taken hundreds of photos.

Detective Inspector Jon Rouse from Taskforce Argos said the arrest represented the "final chapter on a protracted and difficult investigation".

The New Zealander will front the Brisbane Magistrates Court on Friday.
