Singapore has introduced caning as a punishment for male students aged 9 and above who bully others, including through cyberbullying, as a last resort. The punishment will be administered by authorized teachers and will only be used after other measures have been tried. Caning will not be used for female students, who will instead face punishments such as detention and suspension. The move follows a year-long review of bullying in schools and aims to address the issue through stricter measures.
