Two boys, aged 11 and 12, have received conditional warnings after forcing their way into a restricted back cabin of an MRT train on Singapore’s North-South Line. The incident, which occurred on February 21, involved the pair using a tool to open a partition door and pressing a white button inside the restricted area, according to SMRT Trains president Lam Sheau Kai.
Did You Know?
The incident gained significant social media traction months after it occurred; as of June 30, a video of the boys’ actions on Instagram had been viewed more than 281,000 times.
Sequence of Events and Safety Response
The breach occurred while the train was in transit. SMRT Trains president Lam Sheau Kai confirmed that the boys’ actions triggered an on-board alarm, which alerted the train captain in the front cabin. The captain immediately notified the Operations Control Centre, which coordinates the rail system’s daily operations.

Staff stationed at the next stop were alerted to investigate the situation. The two boys alighted at that station, where their actions were captured by CCTV footage. SMRT subsequently filed a police report regarding the unauthorized access.
Expert Insight:
The decision to issue conditional warnings suggests a measured legal response. While the act of forcing open restricted train doors poses clear safety risks and potential operational disruption, authorities likely weighed the age of the individuals and the circumstances of the case before opting for this regulatory measure rather than formal prosecution.
Legal Consequences and Future Implications
The police confirmed that the boys were issued conditional warnings under the Rapid Transit System Regulations. This outcome was reached following a consultation between the police and the Attorney-General’s Chambers (AGC) once investigations were concluded.
While this case has been resolved with a warning, the legal framework remains firm. The decision to prosecute any individual for such offenses rests solely with the AGC. Regarding the broader implications, Lam Sheau Kai stated that SMRT takes a serious view of the incident, noting that unauthorized entry into restricted areas can endanger both the individuals involved and the commuting public by potentially disrupting train operations.
