Belle (not her real name) was only 15 when a man molested her on a crowded train.
Now 18, she can still recall the incident with startling clarity.
She had been on her way to school aboard the train during the morning rush hour, and in the cheek by jowl situation, she felt a man rubbing his private parts against her rear.
"It was very crowded. There were so many people that it was difficult to move in or out of the train. It took some time before I realised what was happening," she recalls.
Unsure if his advances were accidental, she moved her bag to cover her rear.
But that did not deter the brazen molester, who shifted the bag away before continuing with his lewd behaviour.
This time, she spoke out: "I told him to stop touching me, but he just glared at me and said, 'Siao ah?' (Are you crazy?)"
It was as if it was her fault.
A fellow passenger who witnessed the molestation attempted to raise an alarm, but the man quickly alighted at the next station and fled.
Immediately afterwards, she tearfully told her parents and even warned all her friends in the same area to be wary of the molester. But she did not report it.
