Foxconn, the world's largest contract electronics manufacturer, has asked Chinese police to investigate a case in which an employee reportedly committed suicide after being pressured over the loss of an iPhone prototype. Sun Danyong, 25, was tasked with sending 16 fourth-generation iPhone prototypes to Apple this month, but Apple only received 15 when the package arrived, according to Chinese media. Sun reportedly leaped from his apartment window last week, though police are investigating whether he may have been murdered, the Shanghai Daily said.

Allegations of trouble with Foxconn workers in China have bitten Apple before. The U.S. company and its relationship with Foxconn was brought to light three years ago when a British newspaper wrote about allegedly poor pay and long hours for iPod assembly line workers. Apple conducted its own review of the facility but found few violations of its supplier code of conduct. "We are saddened by the tragic loss of this young employee, and we are awaiting results of the investigations into his death," Apple said in a statement. "We require that our suppliers treat all workers with dignity and respect."
