According to court documents cited by The Straits Times, Phoon Chiu Yoke had allegedly failed to wear a mask over her nose and mouth “at all times” while at the Newton Hawker Centre between 7.20pm and 8pm on May 8, 2020.

The 53-year-old woman, charged under the Covid-19 (Temporary Measures) Act, is scheduled to go on trial next Monday.

She is accused of committing the offence during the “circuit breaker” period, similar to Malaysia’s first movement control order, imposed in the republic between April 7 and June 1 last year to curb the spread of Covid-19.

Phoon gained notoriety earlier this month after a video showed her arguing with a safe distancing ambassador at the mall at Marina Bay Sands.

In the clip, an ambassador is seen trying to convince her to wear a face mask, and she responds by asking whether the ambassador has a “badge”.

She is heard saying: “If you have no badge, why are you asking me to do something? Who are you representing?”

When the ambassador replies that she represents the mall, Phoon says: “That’s what you say, I can say that I’m a police (officer).”

Phoon is also believed to be involved in several other instances where she was seen in public spaces without a mask on, with at least two other videos of her circulating online.

One of the videos was supposedly taken at VivoCity in February, and the other was at Clarke Quay Central in December.
