THEIRS was a bitter divorce.

She claimed he had given her a sexually transmitted infection. He accused her of committing adultery and moonlighting as a prostitute.

It got so ugly that the man hired a private investigator (PI) to gather evidence of her nocturnal activities.

And the PI posed as a client and hired the woman to provide sexual services – not once but twice.

The woman, 35, a stall assistant, was allegedly paid $150 on one occasion and $140 on the other. Their encounters at a budget hotel in Changi were secretly filmed and the PI prepared a report which was later tendered in court as evidence.

The man, 51, a delivery driver, told The New Paper that hehired the PI in June.

He said in Mandarin: “She was the one who betrayed me first and yet, she wanted more maintenance.

At the same time, she was making money from other men.

“The humiliation was too much to bear. How could a man stomach this?” The man, who earns less than $2,000 a month, added that he is taking care of their two children, aged 11 and 9.

The couple divorced in July last year after 12 years of marriage.

Matters regarding the division of assets and custody of the children were heard this year.

In March, the Family Court ordered the man to pay her $100 monthly as maintenance and $20,000 as her share of their four-room flat, where the man and the children still live.
