The Chinese government announced Wednesday it had concluded its corruption investigation into British pharmaceutical giant GlaxoSmithKline plc and would be charging three former executives, including the company’s head of China operations and its legal director.

According to the official Xinhua news agency, the 10-month probe was conducted by officers of the Public Security Bureau based in Changsha, a city in Hunan province in central China. The three executives were detained last year as the government investigated charges that they led a bribery campaign targeting doctors, hospitals and officials to prescribe or purchase GSK products.
