Family of Interpol Chief Meng Hongwei have not heard from him since he left Lyon, France for China a week ago.

Chinese state news SCMP reported that a source of theirs said that Meng was taken away by “discipline authorities” for questioning in China, although the Chinese government has made no public comment. Meng’s family have reached out to foreign authorities, fearing disciplinary measures against them as well.

Meng is a senior official in China’s CP government.

Disappearances of officials (or anyone) is not uncommon in China, one of the more severe forms of government discipline. Since President Xi took office in 2012, over a million party officials have received some form of discipline, it has been reported.
