Sex-for-grades trial: Darinne Ko takes the witness stand

The female student at the centre of the sex-for-grades saga has been called to the witness stand.

She is one of 14 witnesses who will be testifying at the trial against law professor Tey Tsun Hang, which started on Thursday morning.

Ms Darinne Ko Wen Hui is expected to give her version of events, which eventually led to Tey being charged with six counts of corruptly obtaining sex and gifts from her in exchange for better grades.

The 23-year-old managed to slip by the media pool waiting for her arrival outside the Subordinate Courts in the morning.

Tey, 41, returned to the courtroom after a short break in proceedings earlier, dressed in a long black lawyer's robe.

He had arrived in court earlier wearing a light grey suit.

The former associate professor at the National University of Singapore, also set up a small easel for documents in front of him as he prepares to defend himself in court.




He has since decided to retain Mr Low, but will conduct his own defence in the case.

The offences Tey allegedly committed took place between May and July 2010.
