On 20 December 1975, 17-year-old Lim Heng Chau was arrested at Woodlands Checkpoint for carrying 499 grams of heroin. Lim pleaded guilty to drug trafficking but since he was below 18 years old at the time of the crime, Lim was ordered to be detained indefinitely under TPP. He was the first convicted drug trafficker to escape the gallows since the introduction of the death penalty for trafficking more than 15 grams of heroin in December 1975, the same month of his arrest for the offence.
