A top Communist Party official in China’s Guangdong province has been placed under investigation for alleged corruption. The probe into Huang Hehong, the party secretary in Conghua, under the jurisdiction of the provincial capital Guangzhou, was announced by the city's Commission for Discipline Inspection on its official Sina Weibo microblog late on Tuesday night. No other details were given. Huang, 50, who was promoted to party chief in July 2010, also served as the standing committee director of the city's legislature and the first secretary of its People’s Armed Forces Department, the Yangcheng Evening News reported. Huang made his last public appearance on Friday when he attended a philanthropic event at the government headquarters. Huang was believed to have close tie with the disgraced former Guangzhou party boss, Wan Qingliang. Both Huang and Wan are from Meizhou, in northern Guangdong. Huang was the deputy director of the provincial water resources department when Wan pushed forward an ambitious 3 billion-yuan (HK$3.8 billion) infrastructure programme that included water conservancy projects in Jieyang, a city south of Meizhou where Wan had served in top posts. It is widely believed that the probe into Wan may be linked to the interrogations of his former top aides and colleagues, including the former vice-mayor of Guangzhou, Cao Jianliao, and a number of senior officials from Jieyang.
