Who is the woman in the sex-for-grades scandal?

The young female that is in the centre of a sex-for-grades scandal involving National University of Singapore law professor Tey Tsun Hang has been identified as 23-year-old Darinne Ko Wen Hui.

According to the charges filed against Tey on Friday, the married professor and former district judge allegedly had sex with Ko twice and obtained an iPod, tailor-made shirts, a Mont Blanc from her from May to July 2010 in exchange for showing favour in his assessment of her academic performance while she was his student at the university.

Ko, who has since graduated from NUS, is a also a former Raffles Girls' School and Raffles Institution (then Raffles Junior College) student.

She was actively involved in the Raffles Cross Country team, even representing her tertiary institution in the inter-school biathlon at East Coast Park in 2007.

One of Ko’s Cross Country team mates, who declined to be named, described her as a “friendly, lively and bubbly kind of person”.

When asked about how Ko performed in school, the source said, “I wasn’t close to her so I don’t know her grades, but my general impression of her is smart, and that she didn’t have issues with her grades.”

Ko started studying at NUS law school in 2008 and was awarded the NUS Faculty Award in 2009.

The bond-free scholarship, now known as the Kent Ridge Undergraduate Scholarship, is reserved for the “brightest talents who possess the will to make a difference”, with recipients described as “well-rounded” individuals who is “consistently among the very best”.

Two coursemates said they were shocked by the news involving Ko, whom they said comes from a well-to-do-family, as she had not struck them as being extremely academically driven.

According to her LinkedIn profile that has since been deleted, Ko worked as an intern at Rajah & Tann LLP between 2008 and 2010.

A Rajah & Tann intern who worked with Ko during that period described her as “bubbly, ready to help, but also a little flirtatious”.

In 2010, Ko worked as a summer associate at O’Melveny & Myers LLP for a year and is said to be currently working as a pupil at a law firm in Singapore.

Forums like Sammyboy have posted pictures of her LinkedIn profile.

Ko's lawyers, Subhas Anandan and Sunil Sudheesan, have said in a statement that the former NUS student will "tell her side of the story when the time comes" and that their client "strenuously denies any corrupt wrongdoing".

"Our client's concern is assisting the Court to come to a truthful and just conclusion of this matter. Our client fully believes that the truth will prevail," they said, as quoted by Today.

    The TT. Audi's diminutive sports car. Since production began in 1998, the two-door coupe has aged with the pugnacity of a grizzled New Yorker, but not in size. And why would it, as the arrival of the TT RS proved, adding some grit makes for a rather captivating dish. And so you'll excuse us for being puzzled by the Audi TT Offroad concept.
