Wang Lijun
In early 2012, the party's Central Commission for Discipline Inspection bolstered its presence within Chongqing as the city's leaders came under investigation. Much of the attention focused on Bo's police chief, Wang Lijun, who may have been under investigation for his role in a corruption case in Liaoning. Growing scrutiny over the city's wiretapping operation against senior leaders also likely fell mainly on Wang. Although details are scarce, several sources have suggested that Wang's resentment against Bo grew amidst the investigations—resentment that was compounded when Wang realized that he and his wife had also been targets of wiretapping under Bo's orders.
