[Zhang Hengyin, Sinopec Group] Zhang used his real name to report to Sinopec Group’s discipline inspection commission the corrupt actions of Nie Sizhi, a unit manager at the Fushun Petroleum Chemical Company, a Sinopec’s subsidiary. In 1996, Zhang was detained by the company’s public security officers and was crippled during an interrogation aimed at extorting a confession from him through torture. For the past fifteen years, Zhang has demanded an investigation into the criminal responsibility of public security officers involved in the case, but his pursuit has yielded no results whatsoever.
