Police in Shanxi province were asked to make self-checks to ensure that neither they nor their relatives have false household registrations, especially after a senior police officer named Fan Hongwei in Changzhi was found to have six fake IDs for himself.

Fan, former deputy director of the public security bureau in Changzhi, was removed from his position on April 25.

Li Zeqing, discipline inspection officer with the provincial public security department, told China Daily on Monday that he could not provide any information about the investigation because it was still underway.
