How One Police Chief Built a Graft Network over Four Decades in Power

(Beijing) -- The fall of the public security chief, Wu Changshun, of the northern port city of Tianjin has rocked local public security system and shed light on the graft network cultivated by Wu over 40 years.

The Central Discipline Inspection Commission (CDIC) said in a statement on July 20 that Wu, chief of the Tianjin Public Security Bureau and vice chairman of the city's political advisory body, was being investigated for "serious discipline violations." The phrase usually means corruption.
