A 19-year-old teenager pleaded guilty to two counts of assault as well as three drug-related charges and was sentenced on 6 December to 21 months probation.
He is also required to stay indoors from 10pm to 6am every day, on top of 60 hours of community service.
He had attacked a 14-year-old boy with his twin brother and 2 other assailants at a youth home in 2018 before committing drug offences the next year.
His twin brother was sentenced to 15 months probation on 29 November.
The twins and 2 other youths confronted the victim, who was in his room at the home at around 10pm in October 2019.
They then rained blows on his head because they felt that he was arrogant.
The victim kept mum about the attack and didn’t seek medical attention after the attack, and the quartet then targeted him again the next month.
They told him to lie down on the bed and used a metal rod to hit his backside four times before leaving.
The victim then told a friend about it and the police were informed about a social worker at the home found out about the incidents.
