According to a report in the Singapore Straits Times, the mother, freelance worker Quek Chin Fern, 42; her son Miguel Lim, 19; and daughter Cheryl Isabella Lim, 18; were alleged to have committed the offence on Aug 12 while parked in the car exit lane at the Sultan Iskandar Customs, Immigration and Quarantine complex at about 3.30pm on Aug 12.

The trio were charged under Section 56(1)(g) of the Immigration Act 1959/63 (Act 155), read out together under Section 34 of the Penal Code and punishable under Section 56(1)(aa) of the same act.

Presiding over the case was judge Salawati Djambari, who allowed bail at RM10,000 with one Malaysian surety for each of the accused and set Sept 5 for the next mention.

If found guilty each accused could be fined not more than RM10,000 (S$3,350) or face a maximum five-year jail term.

Immigration prosecuting officer A Vikneswaran prosecuted the case while counsel Goh Sze Han represented the Singaporeans.

Photos of the trio went viral shortly after the alleged incident and news reports claimed the single mother and her teenage children were arrested after they refused to lower the back tinted window of the vehicle they were in, so the immigration officer could carry out his inspection.

It was also claimed all three verbally abused the officer and hurled accusations at him.

They were headed back to Singapore when the alleged incident occurred.
