An ITE lecturer was jailed for three weeks on Wednesday for distributing seven obscene photographs of his ex-girlfriend to her parents.
Low Peng Hu, 50, had admitted to the offence sometime before Nov 16 last year with a similar charge taken into consideration during his sentencing.
A court heard earlier that the married father of one came to know the 24-year-old victim when she was his student and had helped her and some students in an IT competition.
The pair began a discreet relationship after she moved to another college in 2009 when she often went back to him and another lecturer for help in a project.
During their three-year relationship, he took naked photographs of her in hotel rooms.
The victim later found a new boyfriend last August. Low felt betrayed and accused her of cheating him.
Angry over the break-up, Low sent an anonymous letter to the chief operating officer of the victim's college, stating that the victim and her boyfriend were producing pornographic games in the lab. He also attached five suggestive photographs of her.
Not satisfied, he posted a letter with captioned photographs to her parents, claiming to be the homosexual ex-boyfriend of the victim's boyfriend and that he was suffering from HIV.
The victim and her parents then went to the police.
District Judge Christopher Goh described Low's acts as despicable and cowardly. He could have been jailed for up to three months and/or fined.
