Cleaner Nurhasimah Abdullah is sentenced to a 31/2-year jail term for plotting to ambush the courier. -- PHOTO: SINGAPORE POLICE FORCE By Khushwant Singh A trio who planned to rob a Malaysian money changer's courier pulled off the heist, but a last-minute hiccup apparently led to an unknown person walking off with the loot - $216,236. The law has caught up with the trio, which includes a woman. Nurhasimah Abdullah, a 49-year-old Singaporean cleaner, was on Tuesday jailed 3 1/2 years. She escaped caning because of her gender. Her son Nur Iskandar Shah Mohamed Nasar, 22, is awaiting trial, while the third person, Abdul Jalil Nasar, 26, a Malaysian who had inside information on the movements of the money changer's courier, has been jailed three years and given 12 strokes of the cane.
