Li Tianyi, 17, was found guilty of sexually assaulting the woman in a hotel in February. He was one of five accused. The verdict will be seen as a strict warning to the sons and daughters of China's top-ranked Communist Party officials, who many Chinese say can dodge punishment because of family influence.
Li's father is Li Shuangjiang of the People's Liberation Army (PLA), a singer known for performing patriotic songs on television shows and at official events. As dean of the music department for the Chinese army's Academy of Arts, he enjoys the same treatment as a lieutenant-general, and Li's mother Meng Ge is also a famous singer in the PLA.
But confirming his client would appeal, Chen Shu, one of Li's lawyers, said: "I think this verdict is unjust. This decision is based on evidence that is delayed and verbal testimony which is unreliable."
