France investigating claims of Interpol official Meng's wife

French police opened an investigation after the wife of Interpol director Meng Hongwei reported her husband missing, police sources said on Friday.

Meng's wife, who lives in Lyon, where Interpol is based, contacted the police after not hearing from her husband since he travelled to China in late September, the sources said.

Calls to an Interpol spokeswoman went unanswered.

Meng used to be Vice Minister of Public Security in China, according to Interpol's website.
