China’s largest electric vehicle manufacturer, BYD Auto Co., is under intense scrutiny following the death of a Nanjing auto dealer who accused the company of bilking a government subsidy program and a Caixin probe suggesting the charge may have legs.

The uproar began on March 9, when media outlets in the eastern city reported the suicide of 53-year-old Liu Peng, General Manager of two BYD dealerships: Shangdi Automobile Trade and Service Co. and Sushunya Automobile Trade and Service Co.

Liu reportedly hanged himself in his office.
