A married IT executive is believed to have had sex with two top-ranking public officers being investigated under the Prevention of Corruption Act.

The 36-year-old woman is assisting the Corrupt Practices Investigation Bureau (CPIB) in the cases involving the former chiefs of the Singapore Civil Defence Force (SCDF) and Central Narcotics Bureau (CNB), Peter Lim Sin Pang and Ng Boon Gay.

Sources said the two men had been unaware that she had been intimate with both of them. Both officers are married.

Public discussion has been swirling around the identity of the mystery woman connected to the probe since Wednesday, when a New Paper report said a woman IT executive linked to both Lim and Ng was involved in the case.

In Ng’s case, he had known the woman for over three years and they are believed to have been close since early 2009.

She is said to be an employee of an American multinational software company which she joined about six months ago.

She was previously a sales director at a Japanese multinational company and it is understood the probe is related to her time at this firm, which provides IT storage solutions for businesses and organisations.

The woman, whose husband is a businessman, is believed to have left her previous job about the time the CPIB investigations began. — The Straits Times / Asia News Network
