Airline investigation broadens its scope

Two more executives at China Southern Airlines have been caught up in a corruption scandal, bringing to six the number of senior executives placed under investigation by the top anti-graft watchdog.

Lu Hongye, general manager of the corporation's financial department, and Hu Zhiqun, general manager of its construction development branch, have been held for investigation on charges of corruption, an insider of the corporation revealed to Chinese media.

Lu is alleged to have misused his power to promote Tao Lifang, a female employee in his department who was also reported to be his mistress.
