The employer of the woman who had an illicit tryst with former Singapore Civil Defence Force (SCDF) chief Peter Lim Sin Pang, stood to gain a $400,000 contract if it was awarded a tender by the Home Team agency.

This was revealed in court on Tuesday, by Nimrod Engineering sales manager Lee Yong Chin, who took the stand on the second day of the sex-for-contracts corruption trial.

Mr Lee said Nimrod had quoted about $400,000 to supply the SCDF with radiation detectors and maintenance of the equipment.

On the first day of the trial, the prosecution had linked this contract to the tryst between Lim and Ms Pang Chor Mui, a general manager from Nimrod.

Lim is said to have obtained oral sex at a carpark in May 2010 from Ms Pang, as an inducement for advancing the interests of Nimrod, which was her employer at the time.

Mr Lee, however, said during cross examination by the defence, that Nimrod had been aboveboard when bidding for the SCDF tender.

The case has been adjourned for lunch.

Officers from the SCDF are expected to take the stand later in the afternoon.
