People caught in the Indonesian capital without a mask can lie in a coffin for about a minute as punishment.
Authorities in East Jakarta came up with the unusual measure because they want to force people to think carefully about the consequences of their actions.
“This is what will happen if you become infected with Covid-19,” an offender was told as he took a seat in the open chest. Images of that incident went viral on the internet.
Offenders are not obliged to lie in the coffin, but they can avoid a fine or community service with it.
It is not the first time that authorities in Jakarta have used coffins to urge people to comply with corona rules.
They also previously placed boxes in the city that were provided with a sign with the latest corona figures. More than 180,000 infections and 7,600 deaths have been reported in the country.
