XI'AN - Authorities in Northwest China's Shaanxi Province said Wednesday they have not yet confirmed whether a naked man who appears in sex photos recently posted on the Internet is deputy head of a local school.

Qin Guogang, vice president of the Party School of the Shaanxi CPC Committee, has submitted documents on the matter to provincial CPC discipline inspection, organization and publicity departments, a school source told Xinhua.

The man in the photos resembles Qin, but a police investigation is needed to confirm whether it is really him, said the source.

The photos were still shots from a video shot on August 13, 2013 in the residence of a female postgraduate with whom Qin allegedly had sexual relations, said Qu Jianguo, the woman's lawyer.

There has been no official statement on the scandal.
