So, he befriended boys as young as 10 years old and paid them to perform oral sex on him.
They were paid between S$5 and S$50 for their services.
54-year-old Husain committed these offences in 2015, shortly after his release from jail.
Introducing himself as Abang Choh, he made friends with 3 boys aged 10, 13 and 14 outside Commonwealth MRT station and gave them money to buy contraband cigarettes.
He also gave them his phone number and took pictures of them with his handphone.
The next day, the boys met up with Husain at Star Vista mall and he bought them food and drinks.
When the 13-year-old boy asked to borrow S$50 for a date with his girlfriend, Husain suggested the boys go home with him to his flat.
In his bedroom, Husain told the boys he was gay.
He offered the 13-year-old boy S$50, and the 14-year-old boy S$20 if they would give him oral sex.
They agreed, giving him fellatio while covering their faces with pillows to hide their embarrassment.
Later on, Husain again propositioned a 10-year-old boy into performing oral sex on him.
Husain was finally outed after the 10-year-old boy’s mother made a missing persons report and spotted him with the other boys outside a mosque.
They admitted to what they had done and Husain was arrested.
The incidents took place in 2015.
Husain has pleaded guilty to three counts of sexual assault by penetration has been remanded for further psychiatric evaluation.
He faces up to 20 years’ jail in jail.
