The last person in contact with the 64-year-old Meng was his wife,

Grace, who told reporters before China’s announcement that she had received a WhatsApp message from him containing nothing but a knife emoji after he had arrived in China, which came several minutes after a message which said, “wait for my call.” When she heard nothing more, she alerted French police and reported him missing on Thursday. In a statement posted to Twitter on Saturday, Interpol Secretary General Jurgen Stock said, “Interpol has requested through official law enforcement channels clarification from China’s authorities on the status of Interpol President Meng Hongwei.”

“Interpol’s General Secretariat looks forward to an official response from China’s authorities to address concerns over the President’s well-being,” the statement continued. The French ministry said on Friday that Meng’s family had not heard from him since 25 September, and the French authorities said his wife had been placed under police protection after receiving threats.

In a statement posted on a government website Monday, the authorities said Meng Hongwei, China's vice minister for public security, was being investigated due to his own "willfulness and for bringing trouble upon himself."
The Communist Party of China announces that Interpol president Meng Hongwei is suspected of violating the law and is "under the supervision" of a party anticorruption watchdog. Hours later, Interpol announces that it has received his resignation.
