The party's watchdog for graft and political disloyalty said on its website that Meng Hongwei, China's vice minister of public security, is "suspected of violating the law and is now under the monitoring and investigation" of China's new anti-corruption body, the National Supervision Commission.
Speaking to reporters in the French city of Lyon, Grace Meng said she hadn't heard from her husband since September 25.
The Chinese politician has been heading the International Criminal Police Organization since 2016.
Making her first public comments on the issue, Grace Meng told reporters in Lyon, France, that she thought the knife was her husband's way of trying to tell her he was in danger.
The Central Commission for Discipline Inspection has now confirmed that the official is being under investigation on its official website on Sunday.
"I don't know what has happened to him", she said, adding: "For as long as I can't see my husband face to face speaking to me, I can't be very positive". Grace also said four minutes before Meng shared the image, he had sent a message saying: "Wait for my call".
When Meng was named Interpol's president, human rights groups expressed concern that Beijing might try to leverage his position to pursue dissidents overseas.

When asked about the Chinese announcement on Sunday, France's Interior Ministry said it had no information.
Interpol had said on Friday it had asked Beijing to clarify Meng's situation.
The Associated Press reported that Meng Hongwei is a member of China's Communist Party and his various past jobs likely put him in close contact with Zhou Yongkang, a former Chinese security chief and fellow Communist Party member now serving a life sentence for corruption.
According to a report by the South China Morning Post newspaper, Meng was taken in for questioning by Chinese authorities.
"Interpol's general secretariat looks forward to an official response from China's authorities to address concerns over the president's wellbeing". The paper, which based its reporting on an unnamed source, said the reason for Meng's questioning was unknown.
