BEIJING (Reuters) - The former assistant chairman of China’s securities regulator, Zhang Yujun, will be prosecuted for serious violations of discipline, the country’s graft watchdog said on Friday.

Zhang, who was put under investigation in 2015 after the stock market crash, will be prosecuted for offences including obstruction of investigation, and “disturbing the order of capital markets”, the Central Commission for Discipline Inspection (CCDI) said in a statement on its website.

The former vice chairman of the securities regulator, Yao Gang, will also be prosecuted, CCDI said on Thursday.
