Two Indonesian men were on Thursday convicted of overstaying, illegal departing, and conveying a prohibited immigrant out of Singapore, said the Immigration & Checkpoints Authority (ICA).
They had attempted to leave the country in a Malaysia-registered saloon car via the Woodlands Checkpoint on May 21.
The two men were 48-year-old driver Hasan Bin Maksum and 41-year-old Sofyan Soeb, who was found hiding in the car boot during a routine check.
ICA officers arrested them on the spot.
Found guilty of conveying Sofyan out of Singapore, Hasan was sentenced to a two-year jail term and three strokes of the cane.
Meanwhile, Sofyan was sentenced to three months in jail and three strokes of the cane for overstaying in Singapore, and failing to present his passport to an immigration officer when leaving the country.
ICA added that the vehicle involved in the case has been detained and may be forfeited.
