Prosecutors have been handed the case of a former deputy director of the economic panel under the top political advisory body, seven months after the Communist Party investigated and expelled him.

Yang Gang, 61, was deputy director of the committee for economic affairs of the Chinese People’s Political Consultative Conference, the Central Commission for Discipline Inspection said in an online statement.

“Yang Gang took advantage of his position to take huge bribes and give favours to others. He also committed adultery,” it said.

Evidence of the alleged crimes was handed over to the prosecutors’ office, it said.

Yang was placed under internal investigation in December, five months after he took up the role at the economic panel.

He worked in Xinjiang for more than 40 years, rising from a farm worker in the Xinjiang Production and Construction Corps, the semi-military organisation, at the age of 16 to its deputy commander 22 years later. Yang was made party secretary of Urumqi in 1999, and was the party’s No 2 official in Xinjiang from 2006 to 2010.

He was then transferred to Beijing and became vice-minister of the General Administration of Quality Supervision, Inspection and Quarantine. Wang Lequan, former party boss of Xinjiang, was also transferred to Beijing in 2010 after a riot the year before killed 197 people. Some analysts said he was being blamed for failing to prevent the violence.
