The chief of China's largest brokerage firm is now being probed by authorities in the country, according to Kyoungwha Kim and Alfred Liu at Bloomberg.

According to state-run Xinhua News Agency, managing directors Xu Gang and Liu Wei have already admitted to illegal trading and the spreading of false information.

Citic Securities is part of Citic Group, a state-owned investment corporation.
