Despite the fact the police officer did not suffer any injuries from the "breast assault" — while Ng's face was covered with blood when she was arrested — the magistrate indicated that Ng had precipitated chaos and violence against police by shouting "indecent assault" and sentenced her to three-and-a-half months in prison on July 30.
El 30 de juliol, tot i el fet que l'oficial de policia no va patir cap lesió a conseqüència de "l'atac de pit" (i que la cara de Ng estava coberta de sang quan la van arrestar), el magistrat va indicar que Ng havia fet esclatar el caos i la violència contra la policia per cridar "agressió sexual" i la va sentenciar a tres mesos i mig de presó.
