Mandatory treatment order report called for man responsible for Joo Seng Road fire
A 44-year-old man, Liu Zheyuan, has pleaded guilty to one count of mischief by fire following a May 4 incident at an 18th-floor HDB unit at Block 14 Joo Seng Road. The blaze resulted in 10 people requiring hospital treatment, including two firefighters, and caused estimated damages between $80,000 and $100,000. Following his arrest, Liu was remanded at the Institute of Mental Health, where he was found to be suffering from a delusional disorder.
The Clinical Context of the Incident
According to court documents, Liu’s actions were driven by a diagnosed delusional disorder. At the time of the offense, Liu believed that neighbors were targeting him with laser beams and strong electrical currents sent through the ceiling. He reportedly ignited a pot of charcoal in his living room in an attempt to ward off these perceived attacks.

The fire began at approximately 9.40 p.m. when Liu placed charcoal and fire starters into a stainless steel pot on a metal rack near an open window. The flames eventually spread to a plastic curtain and consumed the unit. While Liu attempted to extinguish the fire, his efforts were unsuccessful, leading him to alert neighbors and contact the Singapore Civil Defence Force.
The fire at the Joo Seng Road unit caused significant property damage estimated between $80,000 and $100,000, impacting the structural integrity and contents of the HDB residence.
Legal Proceedings and Mandatory Treatment
On June 22, the court called for a mandatory treatment order (MTO) report for Liu. In the Singapore legal system, an MTO is a sentencing option that requires an offender to undergo psychiatric treatment to address their underlying medical conditions in lieu of a traditional prison sentence.

The court’s decision to pursue an MTO report follows Liu’s remand at the Institute of Mental Health. This step indicates that the judiciary is weighing the defendant’s mental health diagnosis against the severity of the mischief charge. Liu is scheduled to return to court for sentencing in July.
Samantha Carter notes that the application of a Mandatory Treatment Order highlights a shift toward prioritizing clinical intervention for offenders whose criminal actions are directly linked to diagnosed psychiatric conditions. The outcome of the July sentencing may serve as a benchmark for how the court balances public safety concerns with the necessity of supervised medical treatment for individuals suffering from delusional disorders.
Potential Outcomes for Sentencing
As the case moves toward a final decision in July, the court will review the MTO report to determine if Liu is a suitable candidate for treatment. If the court grants the order, Liu will be required to comply with a structured treatment plan.
Should the court determine that an MTO is not appropriate, the legal process will likely revert to standard sentencing guidelines for mischief by fire. The consequences of this case remain tied to the findings of the psychiatric assessment and the court’s assessment of the risk posed to the community.
