A leading Chinese geologist who reportedly misused research funds for his three mistresses was arrested by police following a tip off from his wife, who furnished a heap of evidence accusing him of corruption and immorality.
His activities came to light following a complaint from his wife Cao Xia who accused him of embezzling funds to the tune of 10 million yuan ($1.52 million).
Cao said she began to notice her husband's infidelities in April and found that Duan had two mistresses and he had given them each a house in Beijing. He had an illegitimate child with one of the mistresses.
Cao, a lawyer had posted information about her husband on a popular online forum, tianya.cn, since June 29, including explicit accounts that claimed to have uncovered wrongdoings by Duan, director of the CAS' Key Laboratory of the Earth's Deep Interior.
Cai showed texts, pictures and photocopies of contracts allegedly signed by her husband with two of Duan's mistresses, state run 'Global Times' reported today.
"I turned to the Internet after my efforts to report the scandal through other means failed," Cao told the daily.
Duan Zhenhao, 52, lied in refund claims for government-paid travel expenses and has been arrested after he was indicted by the Chinese Academy of Sciences (CAS) supervisory and audit bodies, CAS Institute of Geology and Geophysics said in a statement.
"Duan's behaviour seriously harmed the reputation and image of scientists and scientific institutions alike", the statement said.
Meanwhile, "it showed glaring gaps in the supervision of researchers at our institute", the statement said adding no tolerance would be shown for those displaying "misbehaviour and an immoral lifestyle".
Duan lived in the US from 1988 after graduating from the China University of Geosciences.
In 2002, he became a researcher with the CAS, after having been a professor at the University of California.
Cao said Duan had slept with one of his students and helped her with her degree.
"Duan has bought three houses as gifts, worth more than ten million yuan. Where did he obtain so much money?" Cao posted.
Duan admitted to his affairs last week but denied embezzling research funds. He refuted most of his wife's accusations as being groundless.
Duan told the 'Beijing Times' that the women whom he helped were not his mistresses.
One was his neighbour and housekeeper to whom he sold an apartment to her below market price to express his gratitude.
As for the other, Duan explained that he donated his sperm following a request from her husband in 2004.
"They believed that I am educated, so they turned to me," Duan was quoted as saying, adding that he gave the 2,000 yuan to Lin out of sympathy.
Duan was short-listed this year among 314 candidates to become an academician of the CAS this year.
"Several days ago, my wife gave out hundreds of leaflets (about his wrongdoing) in my institute. I have no hope of being promoted this year, or the next," Duan told the “Beijing Times” last week.
