Lau Chi Sing (刘志成[1]loo jeh-chong; 1 January 1966 – 17 November 1989) was a 23 year old male Hong Kong national executed in Singapore for drug trafficking.

[2] After purportedly being recruited to work as a courier for a Hong Kong based drug trafficking organization, Lau was arrested while in possession of almost a quarter of a kilogram of high-quality heroin after checking in for a flight at Singapore's Changi Airport.

Despite vehemently protesting his innocence and stating that he was tricked into smuggling narcotics, Lau was found guilty at trial and sentenced to death, with the Singaporean authorities being ultimately undeterred by pleas for clemency.

[3] Having previously travelled from Bangkok via Kuala Lumpur to Singapore, on 16 October 1984 Lau left the Ghim Pang Hotel in Geylang Road and caught a taxi cab to Changi Airport.

[8] When officer Jamaludin Salleh removed the dry cell batteries from the radio and threw one on the ground, the cap popped off and a white powder spilled out.

Six months before his arrest, he claimed to have been approached by a man named Low Fu Chye in Hong Kong, who asked if he wanted to earn some money "smuggling things", which he thought to mean stolen jewelry.

At a later meeting with Low Fu Chye in Bangkok, he was shown some jewelry and loose diamonds, which he thought were the "things" he was to be paid HK$10,000 for smuggling to Amsterdam.

The Privy Council was previously the highest court of final appeal in Singapore for all cases involving the death penalty, until a change in the law in April 1994.
