SINGAPORE - A teenager, who bore a grudge against his parents for leaving him behind when they went abroad to study, took it out on his younger sister by sexually abusing her.
The 18-year-old Malaysian, who is a Singapore permanent resident, admitted to one of four charges.
Neither he nor his currently 12-year-old sister can be named due to a gag order.
A Community Court heard that the accused was brought up by his grandparents in Singapore until the age of seven. In the interim, he parents had gone to the United States to study.
The victim, who was born there, was brought back to Singapore when she was two years old. Their parents had tried to keep them apart as much as possible since 2011 after the youngster had abused his sister.
On Sept 26, 2013, the victim, then 10, was ill and resting at their own home in the west of Singapore. The accused returned from school and apologised to her for having torn a box belonging to her. She did not say anything in reply.
He then lifted her T-shirt and molested her.
He put his hand into her panties and abused her without her consent. She felt pain and tried to push him away. He stopped only after a few minutes.
After the incident, he told her not to tell anyone about what he had done to her.
The incident came to light five days later when a school counsellor asked the victim about her home environment.
"The accused had committed the offence both out of sexual curiosity and out of vengeance against his family. The accused has a poor relationship with his parents, and begrudges them for leaving him in the care of his grandparents while they went to the United States to study, '' said Deputy Public Prosecutor Gabriel Choong.
The victim was examined and her hymen was found to be intact. But she told a doctor she felt sad, unhappy and angry about the accused's acts.
