BEIJING (AP) — A Chinese drug company says its chief executive has jumped to his death, and official media reported he was under investigation on suspicion of taking bribes.

Sanjing Pharmaceutical Co. Ltd. said Monday that Liu Zhanbin jumped from a third-floor bathroom window in a hospital where he was receiving medical treatment while being accompanied by court guards.

Sanjing said the company has appointed an interim CEO and that Liu’s death has no impact on its operations.

The government’s China News Service and the Communist Party newspaper People’s Daily said Liu was under investigation on suspicion of taking bribes. They gave no details of the investigation.

The Chinese government has launched a sweeping investigation of drug companies as part of efforts to improve health care and rein in drug prices.
