A 35-year-old Indonesian passenger was commended on Friday for her public-spiritedness for assisting Singapore police to solve a series of thefts on board an aircraft this year.

On June 13, the vigilant passenger, a project manager, boarded a Jetstar flight from Singapore to Jakarta at about 8:30 pm, the Shin Min Daily News reported, citing a police statement.

About 15 minutes after the flight had taken off, the female passenger took note of her neighbor taking down four bags from the overhead luggage compartments and rummaging through them. Later her neighbor passed some cash to another man in a different row of seats.

She quickly notified the cabin crew about the suspicious behavior of the pair, resulting in the two men, both Chinese nationals, being flown back to Singapore.

A total of S$437 in cash was recovered from the pair. The money had been taken away from bag of a 37-year-old man seated nearby.

After Singapore police investigated, the two men were each charged with five counts of theft with common intention, read with Tokyo Convention Act, and were sentenced on October 11, 2018, to 19 months’ imprisonment.

On December 21, 2018, the female passenger was commended in the ceremony for her public-spiritedness.

Meanwhile, Singapore police also took the opportunity to remind members of the public traveling overseas to remain vigilant against crime when they are on board aircraft.
