International police agency Interpol has urged China to clarify the status of its president, Meng Hongwei, who has gone missing on a visit to the country.
The agency said it was concerned about the well-being of its president.
His family have not heard from him since he left Interpol HQ in the French city of Lyon on 25 September. China has made no official comment.
The South China Morning Post quotes a source as saying Mr Meng, 64, was “taken away” for questioning in China.
It is not clear why he was being investigated by “discipline authorities” or where he was being held, the Hong Kong-based newspaper adds.
