Two residents of a flat in Compassvale were messaging some friends on WhatsApp amid the Covid-19 outbreak when one of them suggested having a social gathering at the unit.
The court heard that Leong Chee Mun, 37, and his fiancee, Cassie Ong Shi Hong, 32, agreed to host the event at their home on May 8 even though the circuit breaker was still in force.
They later had 16 people over at the unit at Block 295C Compassvale Crescent, the court heard.
Ten of them pleaded guilty yesterday to an offence under the Covid-19 (Temporary Measures) Act. Each of them also had a second charge under the same Act that was taken into consideration during sentencing.
Jackson Tan Chia Ho and Jasmin Tan Ee Lin, both 30, were each fined $3,000.
Poh Yang Ting, 21, Peh Si Qin, 22, Felisa Chua Jia Xuan, 23, Low Wei Hao, 25, Nicman Lim Wei Fong, 25, Chee Min Hui, 27, Kho Zi Ting, 27, and Priscilia Tan Sze Hui, 32, were each fined $2,500.
The cases involving Leong, Ong and six other people are pending.
From April 7 to June 1, members of the public were not allowed to leave their places of residence without a valid reason or meet other people not living in the same place for any social purpose.
Despite this, Jackson Tan and Jasmin Tan were in Leong and Ong's flat since around 6am on May 8 as they had breakfast there, while the other guests turned up from around 9pm that night.
Deputy Public Prosecutor Lee Wei Liang said: "While in the unit, the group... mingled and came into close contact with one another while doing various activities such as eating, drinking alcoholic beverages, playing games and watching Netflix programmes."
A resident in the same block alerted the police to the gathering at around 2am the next day, saying the activities had been going on almost every night.
A police officer, Sergeant Roy Tan, later arrived at the unit. When he rang the doorbell, he heard "hushing" noises coming from inside. But no one opened the front door.
The DPP said: "Sergeant Roy had to knock on the door and ring the doorbell numerous times and wait for about three minutes before (Leong) finally opened the door.
"(Leong) informed Sergeant Roy that he was the owner of the unit, and that he had been sleeping. He also lied to Sergeant Roy that he and (Ong) were the only ones in the unit."
But the policeman called his bluff and said he had heard noises coming from inside the flat.
The court heard that Leong finally admitted that there was a gathering and police later found the guests inside the flat.
Yesterday, DPP Lee urged the court to sentence Jackson Tan and Jasmin Tan to a fine of $3,000 each, stressing that they had stayed in the flat for a far greater duration.
The prosecutor also urged the court to sentence the remaining eight people to a fine of $2,500 each.
For each charge under the Covid-19 (Temporary Measures) Act, a first-time offender can be jailed for up to six months and fined up to $10,000. A repeat offender can be jailed for up to a year and fined up to $20,000.
