Punishment: Five months prison, three strokes of the cane.
In 2010, a Swiss man who had been living in Singapore for two years was arrested for writing MCKOY/BANOS on a train in the Changi Depot. He was two days away from leaving to start a new job back in Switzerland. The other man accused of involvement had already left the country.
The case caused an uproar in Singapore. Not because of the graf--SMRT staff let the piece run for two days, thinking it was an advertisement--but because the train yard was exposed as a soft target for terrorists, a sensitive issue in the region.
In court, the man pleaded guilty to two charges of vandalism and trespassing in a protected place. He received five months in jail and three strokes of the cane.
An appeal to reduce the sentence weirdly increased it by two months. The man was eventually released after less than five months for good behavior. He flew back to Switzerland and was immediately arrested for graffiti offenses there.
