Lyon, France—The Interpol chief has seemingly vanished after a visit to China.

Interpol President Meng Hongwei, who is Chinese and a former Senior Communist Party official, went to his native country for a visit a week ago. He hasn’t been heard or seen since. An official investigation began only after Meng’s wife, alarmed by his silence and threats to her family, notified the French police.

Interpol released a press statement saying, “It is aware of media reports in connection with the alleged disappearance.” Interpol highlighted that “this is a matter for the relevant authorities in both France and China.”

Meng has previously served as director of the Chinese Coastguard and deputy chief of the country’s Oceanic Department. Additionally, Meng was China’s deputy minister of public security. In that role, the 64-year-old Meng was, among others, responsible for the Chinese secret police. That unit conducts domestic counterintelligence, foreign intelligence gathering, and also provides security to senior Communist Party members and government officials.
