The footage prompted criticism not only of the woman’s actions but also of other passengers who appeared to avoid intervening, reviving questions about how Singaporeans respond when disorderly behaviour unfolds in public.

Sabrina Han, 37, was charged with one count of public nuisance on Wednesday and faces a fine of up to S$2,000 (US$1,600) if found guilty.

In court, Han reportedly said she was remorseful for her actions. “I will control my anxiety attack and not do it again,” she was quoted as saying.

The case triggered a storm of online commentary after the video spread, with many users criticising fellow commuters for failing to intervene or alert train staff.

Han was filmed drinking water from a plastic bottle and spitting it out in the direction of other passengers several times inside a train cabin.
