BEIJING, Aug. 28 (Xinhua) -- A Peking University professor has been removed from teaching post after his affair with a woman who allegedly blackmailed him was exposed by local media, according to a statement from the university Sunday.

The statement said that the professor, whose name has not been officially released, had acted unethically as a teacher and seriously blemished the reputation of the university.

An investigation team was organized by Peking University immediately after the report was published on Aug. 22 by Beijing Times.

The school authorities said they removed the professor from his teaching post after they had confirmed the report was true.

According to the newspaper report, a married professor with Peking University had an affair with a young woman in Lijiang, a popular tourist town in the country's southwest Yunan Province.

After he failed to keep his promise to help her enter Peking University, the woman demanded he give her 300,000 yuan (46,951 U.S. dollars) in compensation and threatened to expose their affair, according to the newspaper.

The woman was detained after the professor called the police, it said.
