The case of An Huijun, former director of the Luohu Branch of Shenzhen Public Security Bureau, was still complicated and mysterious. Many senior officials from the Political and Legal Affairs Committee of Luohu District confirmed to the reporter that around October 8th, Shenzhen Discipline Inspection Commission formally implemented "shuanggui" on An Huijun for being suspected of "buying and selling official positions, shielding pornography venues and accepting huge bribes" during her term as director of Luohu Branch of Public Security Bureau. Subsequently, nearly 20 public security cadres were summoned by discipline inspection departments, and currently at least seven of those summoned have been placed under "shuanggui".
