Meng Hongwei, the Chinese head of Interpol, who vanished mysteriously late last month, is being investigated for alleged corruption, China announced on Monday, the latest high-profile target to be ensnared in a sweeping anti-graft campaign led by President Xi Jinping.

Meng, who was also a vice minister of public security in China, was first reported missing in late September after travelling from Interpol's Headquarters in France to China. Concerns over Meng's whereabouts were first raised by wife, Grace, who reported him missing to French authorities in the city of Lyon, where the couple live, last Thursday.
