French police said Friday they were probing the disappearance of the Chinese head of Interpol, who has reportedly been detained for questioning in his home country.
But Interpol walks a fine line between its noble mission - facilitating global police co-operation - and the politics and policies of some of its member countries.
His family have not heard from him since he left Interpol HQ in the French city of Lyon on 25 September.
China has not commented on Meng's whereabouts.
"France is looking into the situation of the President of Interpol and is concerned about the threats his wife has received", the statement said, adding that a "suitable police mechanism" was put in place to guarantee her safety.
Interpol officially requested China's clarification on the fate of the President of the global police organization man Humvee.
Although the commission did not detail the allegations against Meng, its mandate is to investigate corruption cases as part of Chinese President Xi Jinping's anti-graft campaign.
Presidents of Interpol are seconded from their national administrations and remain in their home post while representing the worldwide policing body.
The police asked the wife of MENA, who lives in Lyon, where the headquarters of Interpol.
According to Meng's bio on Interpol's website, he has nearly 40 years of experience in criminal justice and policing, during which he's dealt with issues related to legal institutions, narcotics control, counterterrorism, border control, immigration and worldwide cooperation.
Meng was appointed as the chief of Interpol in 2016 which also sparked controversy as it was alleged that China is extending its crackdown on people overseas.
Meng has a shiny curriculum vitae, having held down various positions within China's security establishment, including as a vice-minister of public security - the national police force - since 2004.
Meng was appointed the head of Interpol in 2016.
Meng, 64, had lived with his wife and two children in France since being elected Interpol president in 2016.
The anti-corruption drive recently drew headlines after the disappearance three months ago of X-Men star Fan Bingbing, one of the country's best-known actresses.
The Chinese Ministry of Foreign Affairs did not respond to a request for comment from reporters.
