Tey Tsun Hang, the National University of Singapore (NUS) law professor currently accused of giving high marks to a student in exchange for sex, is expected to go on trial in the middle of October, according to the Straits Times.

Tey, the director of the school's Center for Commercial Law Studies, was suspended by NUS pending the results of his court case. The school launched an investigation into the claims after the Attorney General's office chose to press charges.

The student, identified as Darinne Ko Wen Hui, is alleged to have had sex with Tey on two occasions, and also given him gifts such a Mont Blanc pen worth S$740 ($594), two tailor-made shirts worth S$236.20, and an iPod Touch. Ko is also said to have paid a bill of his for S$1,278.60.

Earlier newspaper reports said that Ko, 23, spend a few weeks with Rajah & Tann on an unpaid attachment in 2009, and also worked as a summer associate at O'Melveny & Myers in 2010 for a year.

The Straits Times reported that the trial is expected to last nine days.
