SINGAPORE - A man, just two weeks after his release from prison, sexually abused his de facto daughter in the bedroom they were sharing.

The 15-year-old girl, who regarded the then 48-year-old as her father while she was growing up, felt the accused touching her buttocks and moving his hand inside her shorts.

He withdrew his hand from her shorts and proceeded to sleep on the floor beside the bed.

The accused, now 50, admitted to sexual penetration of a minor, drug consumption and failing to report for a urine test. He cannot be named due to a gag order.

Deputy Public Prosecutor Siti Adrianni Marhain said after his release from prison in 2015, the accused moved to the victim's home, where she lived with the rest of her family. Although the victim's mother had remarried, she allowed him to stay in the home as she pitied him.

He slept in the same room as the victim.

In the first week of November that year between midnight and 2am, she was lying on her bed when the accused committed the offence.

The victim, who is now 17, discovered that the accused was not her father as a result of police investigation.

The accused was nabbed for drug offences at a hotel in Balestier Road on July 20, 2016. He had relapsed back to heroin since November 2015.

He had drug-related antecedents in 1987, 1996, 1997 and 2011. He also had other previous convictions between 1985 and 2008.

The accused said he was remorseful for what he had done, and had apologised to his family members.

On Wednesday (June 28), District Judge Imran Abdul Hamid sentenced him to 11 years and three months in jail, saying that nothing the accused had told him amounted to mitigation.

He backdated his sentence to July 31, 2016 and took seven other charges, including three of sexual penetration of a minor, into consideration.

The accused could have been jailed for up to 10 years and/or fined for sexual penetration. The maximum penalty for a repeat drug taker is 13 years and 12 strokes of the cane.

For failing to report for a urine test, he could have been jailed for up to four years and/or fined up to $10,000.

As he is above 50, the accused cannot be caned but was given additional jail time in lieu of the strokes.
