The Xinjiang Police Files attracted global attention when Adrian Zenz, a senior fellow at the Victims of Communism Memorial Foundation, shared them with 14 major news organisations earlier this year.
The result of a hacking attack on police computers in China, public security systems and even computers in detention camps, they shed new light on the situation in the western Chinese region where more than a million Uyghur Muslims have allegedly been incarcerated and - in many cases - subjected to forced labour.
Containing thousands of pictures and confidental documents from two Xinjiang counties, Konasheher and Tekes, they include the internment details of more than 20,000 Uyghur Muslims, aged from 15 to 73, from 2018.
