About the case

It was her second marriage and his first.

But cleaner Loh Ngee Khoon, 59, did not expect his wife of almost 20 years to team up with her young lover to brutally attack him.

Patricia Anne Yong, 60, and her lover, Ahmad Haji Shahul Hammed, 21, will spend four years in jail for the offence.

Ahmad was also ordered to receive six strokes of the cane. He admitted that he had worked with Yong to stab and slash her husband with a knife in their Circuit Road flat at around 5.30pm on Aug 9 last year.

The lovebirds also pressed two pillows against Mr Loh's face that day.

The pair got to know each other in January last year while they were working at Ritz Carlton Hotel, providing laundry services.

At first, she treated him as her godson, but they later became lovers.

Calling the acts "relentless" and "calculated", Deputy Public Prosecutor Joshua Lim urged District Judge Hamidah Ibrahim to jail Ahmad for at least four years.

In his mitigation, Ahmad's lawyer, Mr Jeyapalan Ayaduray, said Yong had told his client about her marital problems.

She wanted him to beat her husband up and teach him a lesson, the court heard.

Mr Jeyapalan said that Ahmad is mildly retarded and had always looked to her for instruction.

He said: "She was unforgiving and directed (Ahmad) to smother (Mr Loh) jointly with her."

"The brutality is shocking," said Judge Hamidah on Monday before handing out Ahmad's sentence.

For attacking Mr Loh with the knife, Ahmad could have been jailed up to 15 years and fined or caned. For pressing a pillow against Mr Loh's face, he could have been jailed up to two years and fined up to $5,000.
