If you walk along Serangoon Road this weekend and drink from a can of beer, you will be breaking the law.
This is because of the two-day alcohol ban that is being put in place following last Sunday's riot.
The police said during a media briefing last evening that the ban prohibits the sale and consumption of alcohol in the Little India area.
They will also be enforcing the Public Order (Preservation) Act (POPA), which means that no one can be seen consuming alcohol in public in Little India.
This means they can confiscate the alcohol, and anyone behaving in a drunk or disorderly manner may be arrested under the Miscellaneous Offences (Public Order and Nuisance) Act.
Those found guilty of public drunkenness can be fined up to $1,000 and jailed for up to a month. Repeat offenders face a higher penalty.
Even if you hold a can of beer and do not drink from it, you might be asked where you got it from, the police said.
The ban comes after Singapore's first riot in nearly 50 years. So far, 31 men have been charged with rioting.
The temporary alcohol ban will start from 6am on Saturday and last till 6am on Monday, covering a wide area bounded by Dorset Road, Beatty Road, Jalan Besar and Mackenzie Road.
This will include restaurants, coffee shops, bars, liquor stores and even hostels and hotels, all of which hold about 374 liquor licences in the area.
