• The wife missing Interpol President Meng Hongwei says her husband sent her an image of a knife before he disappeared during a trip to their native China.
• Grace Meng told reporters she thinks the knife was her husband's way of trying to tell her he was in danger.
• Meng was first reported missing after traveling to China September 29.

The wife of the missing president of Interpol says her husband sent her an image of a knife before he disappeared during a trip to their native China.

Making her first public comments on the mystery surrounding Meng Hongwei's whereabouts, Grace Meng told reporters in Lyon, France on Sunday she thinks the knife was her husband's way of trying to tell her he was in danger.

She says she has had no further contact with him since the message that was sent on Sept. 25. She says four minutes before Meng shared the image, he had sent a message saying, "Wait for my call."

She says she hasn't heard from him since and does not know what happened to him.

Meng, a Chinese national, was first reported missing on September 29. Interpol said in a statement it was "aware" of the Meng's alleged disappearance, but that France and China was responsible for the investigation.

Rights groups previously said that Beijing could use Meng's position to arrest and deport its critics abroad.

Interpol is headquartered in Lyon.
