A Hong Kong court has sentenced a former teacher to 18 months in prison for molesting a student on two separate occasions in 2020, with the presiding judge rejecting any possibility of a reduced sentence given the gravity of the offences. District Judge Gary Lam Kar-yan delivered the verdict at Tsuen Wan Court against defendant Cheng Hon-sze, now 32, who was found guilty of two counts of indecent assault involving groping and forcing the victim to perform an obscene act in May and October 2020.
The case represents a stark example of institutional failure and the abuse of trust that occurs when educators cross fundamental professional boundaries. Cheng, who taught the girl across multiple years including Forms One, Two and Four to Six, also directed the school's marching band in which the victim performed as a trumpeter. This dual relationship—combining academic authority with extracurricular influence—created multiple vectors through which he could exploit and isolate his victim. The 11-year age gap between teacher and student formed a central consideration in the sentencing, with the judge emphasizing that no reduced penalty could be justified despite Cheng's claims that this was his first conviction.
While Cheng faced nine counts of indecent assault in total, the court cleared him of seven additional charges. The judge's reasoning revealed a troubling gap in how the law defines consent and resistance: the girl on those occasions had not explicitly refused his advances or the acts were deemed insufficiently indecent under legal definitions. This distinction underscores a persistent challenge in prosecuting sexual abuse cases involving minors, where the burden of demonstrating active refusal can obscure the inherent power imbalance between adult authority figures and children.
Criminal proceedings disclosed that the defendant repeatedly engaged in intimate contact with the victim across the school's music storage room and other locations, establishing a pattern of calculated predatory behaviour spanning years. The trauma inflicted extended far beyond the two convictions: according to prosecution evidence, the abuse occurred intermittently from November 2019 through June 2024, during a critical developmental period when the victim ranged from 14 to 19 years old. Such prolonged exposure to abuse during adolescence compounds psychological damage significantly.
Psychological assessments presented to the court revealed profound and ongoing harm to the victim's mental health and worldview. According to a trauma report, the girl continues struggling to process her complex feelings toward her abuser—a phenomenon clinical psychologists recognize as common among abuse survivors who receive mixed messages of care alongside harm. The report documented how she had developed what the judge termed "twisted values," wherein she felt compelled to tolerate abuse if the perpetrator demonstrated any kindness. This psychological distortion arose from her inability to fully comprehend the severity of what had occurred to her during such formative years.
The victim's experience demonstrates how child sexual abuse by authority figures creates layered psychological consequences extending well into adulthood. The report indicated she had internalized an extremely contradictory emotional state lasting several years, leading her to suppress natural disgust responses and abandon personal boundary recognition. Exposure to such betrayal during a crucial developmental window had left her viewing the world as fundamentally unsafe and untrustworthy, fearing that anyone could conceal harmful intent beneath a facade of care. Judge Lam acknowledged in his remarks that the victim faces an extended journey toward emotional recovery, expressing hope that she would emerge from this trauma.
In determining the sentence, the judge imposed one year of imprisonment for each of the two assault convictions, then ordered them served as partially consecutive sentences, resulting in the 18-month total. This structured approach acknowledged the severity of each individual act while ensuring the overall penalty reflected the cumulative harm. The sentencing considered not only the indecent nature of the specific acts but also the documented psychological damage the victim sustained.
Clinical psychological evaluations of Cheng himself provided insight into his criminal motivations, though such analysis offers limited consolation to the victim. The assessment concluded that the defendant struggled with age-appropriate relationship formation and fundamentally failed to recognize the power imbalance inherent in his position as educator and adult authority figure. The psychologist noted that Cheng had not grasped that such behaviour violated social and professional norms, suggesting a deeper problem than simple impulse control. Despite these deficiencies, the evaluation indicated a low to moderate likelihood of reoffending, contingent on his engagement with professional rehabilitation services.
As part of his sentence, Cheng will be required to participate in follow-up work with social workers and to receive professional psychological intervention through the Correctional Services Department's rehabilitation programme. This mandatory therapeutic engagement reflects growing judicial recognition that prison sentences alone insufficient address underlying pathologies driving sexual offences. The judge's acceptance of the psychologist's recommendation for professional help signals an attempt to reduce recidivism risk, though critics often question whether offenders genuinely benefit from such interventions.
Cheng's defence counsel had argued for mitigation based on his lack of prior relationship experience, suggesting this immaturity had caused him to develop inappropriate feelings that overwhelmed his judgment. His legal team conceded that the teacher-student boundary should never have been crossed and urged the court to consider his relative youth at the time of the offences. Mitigation letters from his sister and a friend portrayed the conduct as uncharacteristic, and evidence emerged that Cheng had applied to pursue a master's degree at Polytechnic University after being barred from teaching. These mitigating circumstances proved insufficient to sway the judge, who maintained that the seriousness of the offences and their documented impact on the victim precluded leniency.
The case carries implications beyond Hong Kong's borders, resonating particularly across Southeast Asia where institutional safeguarding mechanisms for students remain inconsistently developed. The conviction and sentencing demonstrate that courts can hold educators accountable for abuse of trust, though the extended period between initial offences and prosecution highlights investigative and reporting delays that often plague such cases. For Malaysian and regional educators and school administrators, the case underscores the necessity of robust institutional policies regarding teacher-student interactions, transparent reporting mechanisms, and trauma-informed support systems for identified victims.
