Hill Street 1984 to 1998

location： 62 Hill Street

The Hill Street premises, located next to the Central Fire Station, previously served as the Worker's Party office of J.B. Jeyaretnam before being taken over by the Corrupt Practices Investigation Bureau (CPIB) in 1984. This new location was a significant upgrade from their previous site at Stamford Road, featuring a briefing room and recreational room, although the equipment remained outdated. The bureau possessed only a single mobile phone, an old and cumbersome model.

During this time, several changes were made to improve the CPIB's operations. Notably, 1989 saw the establishment of a Complaints Evaluation Committee, chaired by the Director of the CPIB and involving the heads of the investigations unit. This committee evaluated complaints and decided on follow-up actions. Additionally, the government enacted the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act in the same year, which allowed for the seizure of benefits obtained through corrupt means, depriving offenders of the proceeds of corruption.

The Hill Street era also witnessed several high-profile cases, including investigations into former Minister of National Development Teh Cheang Wan, former Public Utilities Board Deputy Chief Choy Hon Tim, and former regional manager of the Asia Pacific Division of the Government of Singapore Investment Corporation Eddie Taw Cheng Kong. The CPIB handled these cases without fear or favour, demonstrating that no one was above the law.
