They were discussing what they saw when a passer-by, a 62-year-old food delivery rider, asked them what they were doing. Ong told him that there was supposed to be something in the sky resembling "Guan Yin Ma", so the delivery rider also began taking pictures.
However, he failed to see anything that resembled the Goddess of Mercy, the prosecutor said.
About five minutes later, he confronted Ong and alleged that Ong was a scammer. The delivery rider also began taking pictures of Ong and his wife. Ong asked the rider to stop and to delete the pictures, but the rider refused.
He challenged Ong to a fight and threatened to have Ong or his wife beaten up if they stepped foot in Lorong 20, Geylang.
Angered by this, Ong pushed the delivery rider on his chest and kicked his knee. The rider lost his balance and fell against a nearby stone bench.
