A man posed as a good Samaritan to molest two vulnerable women on separate occasions.
Ang Ah Lak even threatened to hold one of the victims in his flat for three days.
The 51-year-old was jailed for three years and 10 months yesterday after pleading guilty to three molestation charges.
His first victim was a 35-year-old woman who had been receiving treatment for schizophrenia at the Institute of Mental Health.
She was leaving a recovery group session at around 4pm on Nov 20 last year when Ang approached her and started a conversation. When she told him she was unemployed, he said he could offer her a job and the next day, they met at a bus stop near Causeway Point in Woodlands.
He said he needed to return to his flat in Marsiling Road first and asked her to go along. About 20 minutes after getting there, the woman began to feel uncomfortable and wanted to go home, the court heard.
Deputy Public Prosecutor Marshall Lim saidAng threatened to tie her up and keep her in the flat for three days and nights. He then molested the woman, who left the flat soon after. She alerted the police the next day.
Ang met his second victim while she was sitting alone in a playground near his flat at around 1am on Feb 9 this year.
She had left her boyfriend's flat after a quarrel and had nowhere else to go, the court heard. Ang approached the 18-year-old and told her she should go with him to his flat.
DPP Lim told District Judge Marvin Bay that Ang told the girl he had "hosted many girls before and that he is very nice to girls".
She agreed but when they got to the flat, Ang undressed in front of her and went to take a bath. Trying to leave, she found the gate locked.
Ang later came out of the bathroom naked and molested her. He also said that he wanted to have sex with her.
To escape, the woman lied that they could do so in her home. Ang agreed, but as they were walking downstairs, they ran into her 21-year-old boyfriend, whom she immediately told about what happened. Ang fled.
Judge Bay said: "Ang had targeted successive victims by exploiting their vulnerabilities, by offering false hospitality and promises of employment... and proceeded to gratify his perverse desires on these hapless women."
