In an effort to restore public trust in the nation's police, the National Police Agency on Saturday held an urgent meeting of 46 prefectural police chiefs following a series of recent scandals over misconduct within the force.

The meeting was prompted particularly by the recent revelation of misconduct by the Niigata Prefectural Police in dealing with a case last month in which a girl missing for nine years had been found.

The case led to the resignations of Yoshiyuki Nakada, head of the NPA's Kanto Regional Police Bureau, and Koji Kobayashi, chief of the Niigata Prefectural Police.
