In 1999, Vincent Lee Chuan Leong (李泉梁 Lǐ Quánliáng), a Singaporean ex-convict, together with two illegal immigrants from China, kidnapped a 14-year-old female student in Singapore. The trio abducted the teenager into their rented car, and then demanded S$500,000 ransom from the girl's father, a wealthy second-hand car dealer. Eventually, through negotiations, the ransom was lowered to S$330,000, and upon the agreement to the amount, the ransom was paid and the girl was subsequently released without harm.
Shortly after releasing the girl, Lee was arrested by the Singapore Police Force for kidnapping the teenager for ransom, and his two accomplices Shi Song Jing and Zhou Jian Guang, were also caught. Lee was found guilty of kidnapping by ransom and sentenced to life imprisonment. Both Shi and Zhou received the same sentence for the crime in a separate trial. After serving twenty years, ten months and nine days in jail, Lee was granted parole and is currently released from prison since 22 June 2020.
