BEIJING (BLOOMBERG) - The chairman of mid-sized Chinese brokerage Changjiang Securities Co. is under investigation by the Communist Party, adding to the list of financial industry executives and regulators facing probes by the party or the police.

Mr Yang Zezhu is suspected of violations of discipline for "personal reasons," the company told Shenzhen's stock exchange in a statement on Wednesday (Jan 6).

Changjiang was informed of the investigation in a notice that it received on Tuesday from the party's discipline inspection committee in Hubei province.

The brokerage said it is operating normally.
