Ng Theng Shuang (黄庭双 Huáng Tíngshuāng; 1 January 1966 – 14 July 1995) was a Penang-born Malaysian and criminal who was one of the two armed robbers involved in a robbery attempt of the Tin Sing Goldsmiths at South Bridge Road in November 1992.

Ng, together with his Malaysian accomplice Lee Kok Chin, later engaged in a shoot-out with Cisco guard Karamjit Singh, whom he injured in the leg.

It resulted in one of the robbers, Ng Theng Shuang, who was armed with a 9mm Luger semi-automatic pistol, to fire his gun at Singh, injuring the officer's right thigh.

Two other people, a 57-year-old salesman named Ou Kai San and a 39-year-old female customer Rosie Kee Lye Choon, were also injured during the exchange of gunfire.

[8] After Lee fell off the motorcycle, Ng went on to rob a woman named Elizabeth Jeeris of her station-wagon and used it as a getaway vehicle to drive away.

[9] While Ng managed to escape, his accomplice Lee Kok Chin, who was mortally wounded in the chest, was pronounced dead at the spot where he had fallen from the motorcycle.

The police, who managed to identify Lee through his fingerprints, also found a semi-automatic pistol, a Llama .38, and two live grenades in his possession.

In the most recent offence he committed in Singapore before the current case, Lee also used a gun to rob a moneychanger and his brother at gunpoint at Golden Note Trading on North Bridge Road.

Singh was awarded with a commendation certificate, a plate from the Certis Cisco and even received a double promotion from constable to corporal for his heroic actions and professional discharge of his duties during the incident.

[14] In October 1993, nearly a year after the shooting incident, a coroner's court ruled that Lee Kok Chin's death was one of a justifiable homicide, as the officer Karamjit Singh had rightly exercised his right to self-defense in the face of the robbers being armed and the customers, employees and himself at the goldsmith shop were at risk of being injured or killed in this situation.

Ng was extradited back to Singapore, where he was charged on 31 December 1993 with discharging a firearm to cause hurt to Karamjit Singh and the two bystanders.

Ng was represented by Simon Tan and P. Suppiah, and the case itself was prosecuted by both Chan Seng Onn and Muhammad Hidhir Majid.

The judge also found that the fingerprint tests had effectively implicated Ng for his involvement of the crime, for which the prosecution had proven its case beyond a reasonable doubt.

[31][32][33] As such, 28-year-old Ng Theng Shuang was found guilty of two counts of illegally discharging a firearm to cause hurt under the Arms Offences Act, and he received two death sentences for each of these two charges.

[38] As a result, Ng's wife was shunned by most of her friends, and she never went outdoors for a period of time since the arrest was widely-known inside the small town of Bukit Mertajam.

[44] On the Friday morning of 14 July 1995, 13 days after the loss of his clemency plea, 29-year-old Ng Theng Shuang was hanged at Changi Prison.

[45][46][47] In the aftermath, Singaporean crime show Crimewatch re-enacted the South Bridge Road shooting case, and it first aired in March 1996 as the first episode of its annual season.

Singh stated that he left the incident behind him and moved on, but he remained modest about his deed, and still kept newspaper clippings about the case, which he planned to show to his grandchildren in the future.
