The South China Morning Post reported on June 3, 2017, that a source with the Chongqing Municipality who declined to be named said He Ting, the Municipal Police Bureau Chief and the Executive Deputy Mayor, “was taken away by discipline inspection personnel for investigation on March 31”. 

(Comment: This is being linked to the competition for seats on the Politburo Standing Committee with sources reportedly telling South China Morning Post that He Ting “had boasted about his close ties to Sun” -- the Chongqing Party Secretary Sun Zhengcai.)
