According to a BBC report, data hacked from Xinjiang police has recently revealed how Beijing has conducted mass detention of Uyghurs.

The hacked documents were transferred to Dr. Adrian Zenz, and he later shared them with BBC. Adrian is a scholar at the US-based Victims of Communism Memorial Foundation, and the Chinese government once sanctioned him for his influential research on Xinjiang.

The files contain over 5,000 photographs taken by the police of Xinjiang. Over 2,000 were reportedly detained by guards armed with batons standing nearby.
