A 32-year-old man and a 36-year-old woman were arrested for suspected drug offences.
Two sachets of suspected controlled drugs and various drug paraphernalia were found concealed within the woman’s clothing, said the authorities.
They added that the drugs seized have an estimated value of more than S$249,800 (US$184,000) and can feed the addiction of about 1,120 abusers for a week.
Anyone found guilty of importing more than 15g of pure heroin (diamorphine) may face the mandatory death penalty.
