Yet another company in the pharmaceutical industry is investigating allegations of bribery and corruption, and this time it is French drug company Sanofi.

Sanofi said it is conducting an internal investigation amid allegations made by a whistleblower that employees bribed doctors in the Middle East and East Africa between 2007 and 2012, encouraging them to boost sales of Sanofi drugs in those markets, according to e-mails reviewed by The Wall Street Journal.

Sanofi said it has notified the Department of Justice and the Securities and Exchange Commission of the allegations.

The French drug maker is not the only one to come under the spotlight for bribery allegations. In September, a Chinese court found GlaxoSmithKline’s China subsidiary guilty of bribery, and fined the company a record $489 million—the largest corporate penalty the country has ever imposed.
