The first person to be tried before two judges in the High Court and sentenced to death for a capital case was 36-year-old armed robber and gunman Teo Cheng Leong, who fired two missed shots at a police officer while trying to evade capture for an armed robbery in March 1969; he was convicted of unlawfully discharging his firearm in February 1970, for which the crime carries either a sentence of life imprisonment or death before the enactment of the 1973 Arms Offences Act (which mandates the death penalty for illegal discharge of firearms). Teo was subsequently hanged, presumably in 1971 or 1972, while two out of his three other accomplices of the robbery were convicted and served 10 years' imprisonment each for armed robbery; the third accomplice was never found till today. Another first case was the kidnapping and murder of Ong Beang Leck, where five men were involved in the abduction of 19-year-old Ong Beang Leck, who was the son of a rich towkay in Singapore, and murdered him after luring him into a rented car on 24 May 1968; after Ong's death, the killers even extorted ransom from Ong's father Ong Yew Kee before their arrests three weeks later. Three of the five kidnappers - Lee Chor Pet (the mastermind and a close friend of the victim Ong Beang Leck), Lim Kim Kwee and Ho Kee Fatt - were convicted of murder and sentenced to death on 11 June 1970 while the rest - Chow Sien Cheong and Richard Lai Chun Seng - escaped with jail terms of four years each for abetting the abduction and possessing the ransom money. The three convicted killers were eventually hanged on 27 January 1973.
