Singaporean authorities on Sunday raided an outdoor area around City Plaza, where two hawkers were arrested for illegally offering cooked food to foreign domestic workers in the open.

The inspection by the National Environment Agency (NEA) was conducted after citizens’ complaints at a field at Paya Lebar, near City Plaza, a well-known spot for Indonesian domestic workers to rest and catch up with their friends on weekends, the Shin Min Daily News reported.

According to a report by The New Paper, two hawkers who were allegedly selling mee bakso (Indonesian beef ball noodle soup) were taken away by officers for illegal sale of food, according to an NEA spokesman.

netizen posted photos and videos of the aftermath of the inspection. Red plastic sheets used by domestic workers as picnic mats were unattended, with bowls of mee bakso clearly left out in the open.

Many bags and containers of cooking materials and raw food items owned by the hawkers were resting on the ground next to the tree, and officers were seen emptying a pot that had been cooking food on a portable stove into a trash bag.

The NEA has advised the general public to report any illegal hawkers by calling the agency’s 24-hour contact center at 1800-CALL-NEA (1800-2255-632).

People found illegally hawking food are liable to seizure of their goods, and may be fined S$300, S$400 and S$500 (US$219, US$292 and US$265) for the first, second and third offenses respectively. Upon the fourth and subsequent offenses, they are to be prosecuted in court.
