A Hong Kong court on Monday delivered an 18-month prison sentence to former educator Cheng Hon-sze, now 32, following his conviction on two counts of indecent assault against a minor student. The case, heard at Tsuen Wan Court, centred on sexual misconduct perpetrated in May and October 2020 when the victim was just 15 years old. District Judge Gary Lam Kar-yan determined that the gravity of the offences warranted a custodial sentence without any reduction, regardless of it being the defendant's first conviction.
The nature of the assaults involved inappropriate physical contact and coercion to perform indecent acts. Cheng had admitted to repeatedly engaging in intimate conduct with the student across multiple locations, including within the school's music storage room. Although prosecutors initially brought nine separate counts of indecent assault against the teacher, the court cleared him of seven charges after determining that the victim's lack of explicit refusal or the non-inherently indecent character of those specific incidents fell below the threshold for conviction. Nevertheless, the two proven counts resulted in one year of imprisonment each, structured as a partially consecutive sentence to reach the final 18-month term.
The professional relationship between perpetrator and victim added considerable weight to the court's judgment. Cheng had taught the girl across multiple year levels—Forms One, Two, and Four through Six—and held an administrative position overseeing the school's marching band, in which she participated as a trumpeter. This supervisory capacity represented a fundamental breach of trust and institutional safeguarding. The judge specifically highlighted the 11-year age gap separating the two parties, the explicit nature of the sexual misconduct, and the demonstrable psychological harm inflicted upon the young victim.
Investigations revealed a pattern of abuse extending far beyond the two convicted incidents. The victim had endured repeated molestation from November 2019 through June 2024, a period during which she aged from 14 to 19. This extended timeline suggests institutional failures in protection mechanisms and raises questions about how such conduct could persist unchecked within an educational environment. The psychological toll on the survivor—who experienced manipulation spanning multiple years during her formative teenage years—became evident in clinical assessments presented to the court.
A trauma evaluation of the victim documented profound emotional damage stemming from the abuse. She found herself trapped in a contradictory mental state where she simultaneously credited the perpetrator with helping her whilst recognising his capacity to cause harm. This psychological compartmentalisation forced her to abandon normal protective boundaries and override natural disgust responses. The report characterised her as having developed distorted value systems wherein she could rationalise accepting mistreatment from someone who displayed occasional kindness or mentoring. Judge Lam, referencing the clinical findings, noted that she had developed "twisted values" that normalised the abuse.
The developmental context intensified the culpability. During adolescence—a critical period for psychological formation—exposure to this predatory conduct and emotional manipulation damaged the victim's capacity to perceive interpersonal relationships as safe. She came to view the world through a lens of betrayal and untrustworthiness, believing that anyone, regardless of surface friendliness, might ultimately hurt her. The judge acknowledged that her emotional recovery trajectory would prove lengthy and uncertain, offering personal encouragement and directing her toward professional mental health support.
The defence strategy centred on portraying Cheng as emotionally immature rather than predatory. Legal representatives argued that his limited romantic experience had led to confused feelings that overwhelmed his judgment. They emphasised his youth at the time of the offences and requested leniency on those grounds. Supportive letters from his sister and a friend characterised the behaviour as anomalous and contrary to his usual demeanour. Additionally, the defence noted his academic pursuits—a master's degree application at Polytechnic University—following his removal from the teaching profession, suggesting rehabilitative capacity.
A clinical psychologist's assessment, however, presented a more concerning analysis of Cheng's psychological profile. The report identified difficulties in forming age-appropriate romantic relationships and a failure to comprehend the power dynamics inherent in teacher-student interactions or the social unacceptability of his conduct. Significantly, the assessment estimated a low to moderate likelihood of reoffending but emphasised his apparent willingness to accept professional intervention. Based on these findings, Judge Lam mandated that the Correctional Services Department provide psychological rehabilitation during his incarceration.
The sentencing decision reflects Hong Kong's judicial approach to institutional sexual abuse cases, where the breach of professional duty and exploitation of vulnerable minors receive stringent treatment. The court's rejection of mitigation arguments—particularly the defendant's relative youth and claimed lack of intent—demonstrates judicial recognition that such excuses cannot diminish the culpability of authority figures who exploit their institutional position. The 18-month term represents a measured response that acknowledges both the seriousness of proven offences and mitigating factors whilst prioritising victim protection and societal safety.
For Malaysian and Southeast Asian observers, the case illuminates ongoing vulnerabilities within educational systems across the region regarding child safeguarding and institutional accountability. Teachers occupy positions of profound trust and authority over minors, yet documented cases across multiple jurisdictions suggest inconsistent implementation of protective protocols. The extended duration of Cheng's abuse—spanning years with multiple victims potentially unreported—underscores how institutional cultures sometimes fail to respond effectively to warning signs or survivor disclosures. Hong Kong's judicial handling provides a regional benchmark, though questions persist about preventative measures, reporting mechanisms, and institutional transparency that might have prevented or arrested the abuse earlier.
