SINGAPORE - A second person has been remanded at the Institute of Mental Health (IMH) for psychiatric evaluation after an episode in public involving face masks.

Kasturi Govindasamy Retnamswamy, who refused to don a mask properly when told, is said to have later assaulted a police officer who tried to ascertain her identity.

The incident, which led to her arrest, happened at the Sun Plaza mall in Sembawang on May 7 and was captured on video.

Kasturi, 40, was in court on Saturday (May 9) to face five charges. They include the use of abusive words and criminal force on a public servant.

She is expected to be back in court on May 22 after her remand in the IMH.

In a statement on Friday, police said the Singaporean woman insulted mall staff and hurled vulgarities at a security officer who was trying to get her to put on her mask correctly.

A widely-shared video of the incident shows a woman taunting a mall employee while demanding he removes his face mask to speak to her.

Police said mall staff made the call for help at about 2.10 pm. When police officers requested to see her identity, she allegedly started peeling off the address sticker on her identity card.

"When one of the police officers tried to stop her, the woman assaulted the police officer and remained uncooperative," said the police, noting that the woman had been fined $300 on April 29 for not wearing a mask at the same mall.

"Everyone should take the circuit breaker measures seriously. The police will not tolerate such blatant disregard of the law and wilful breaches of safe distancing measures."

Investigations are ongoing.

Kasturi is the second person to be remanded at the IMH for psychiatric evaluation after an incident in public.

Paramjeet Kaur, 40, who made headlines after videos emerged of her claiming to be a "sovereign" when confronted for not wearing a mask in public, was charged on May 5 with one count of being a public nuisance and three counts of violating Covid-19 rules.

The Singaporean will be back in court on May 19.

Those convicted of voluntarily causing hurt to deter a public servant from carrying out public duties will be liable to a maximum jail term of seven years and a fine or caning, provided that in exceptional circumstances imprisonment need not be imposed.

If found guilty of harassment by using insulting or abusive language, perpetrators face up to six months' jail, fined up to $5,000, or both.
