A 40-year-old Singaporean man has been charged over false claims he allegedly made that supermarkets would open only two days a week as part of enhanced measures here.

Kenneth Lai Yong Hui is accused of posting the false information on Facebook group "Taxiuncle", saying he had received information that enhanced Covid-19 circuit breaker measures would be rolled out on April 18.

The Singaporean was hauled to court yesterday and charged with communicating a false message.

The Straits Times understands that Lai is a taxi driver.

He is believed to be the first person to be charged with the offence during the coronavirus outbreak.

Those convicted can be jailed for up to three years and face a maximum fine of $10,000.

According to court documents, he allegedly posted the false message saying he had "intel" that extended measures in Singapore would purportedly be imposed on April 18.

Police revealed details of his alleged message yesterday.

They said that between April 15 and 16, Lai wrote: "Food courts, coffee shop (sic) all to close. Supermarkets will only open two days a week.

"Better go stock up your stuff for the next month or so. Government officials (were) in (a) meeting yesterday and will finalise measures tomorrow."

He is said to have done this in a Bishan flat.

Yesterday, Lai told the court that he intends to plead guilty, and regrets his actions.

He said: "I am very sorry and remorseful for what I had done."

He will be back in court on May 27.

In their statement, police said they will not hesitate to take action against those who transmit or communicate falsehoods.

"Members of the public should refer to official sources for information and avoid spreading unsubstantiated information or false rumours, as these may cause fear and public alarm," police added.

The circuit breaker period started on April 7 to curb the spread of the coronavirus here, and has been extended to June 1.

However, supermarkets, as well as foodcourts, coffee shops and restaurants providing takeaways, remain open.

All standalone food and beverage outlets, hairdressing salons and barber shops were shut from April 22.
