The Singapore Prison Service (SPS) is a government agency of Singapore under the Ministry of Home Affairs. Based in Changi Prison Complex in the eastern part of Singapore, the service runs 14 prisons and drug rehabilitation centres in the country. Its responsibilities encompass the safe custody, rehabilitation and aftercare of offenders, and preventive education.

History

Under British colonial rule (1825–1965)

On 18 April 1825, the first batch of penal convicts arrived in British-ruled Singapore and were housed in temporary huts along the Bras Basah Canal. The philosophy of deterrence through punitive measures rather than rehabilitation was adopted. In 1847, Outram Prison was built at Pearl's Hill but overcrowding remained a major issue and a continued punitive approach in prison management led to a high rate of recidivism.

In 1936, Changi Prison was opened and operational as a maximum security prison and as a training ground for the reform and rehabilitation of its inmates.

From 1942 to 1945 during World War II, Changi Prison was used as a prisoner-of-war camp.

After the war, the Singapore Prison Service was institutionalised as a government department in 1946 and G.E.W.W. Bayly became its first Commissioner.

Post-independence (1965–1999)

After Singapore gained independence in 1965, Quek Shi Lei was appointed Director of Prisons on 1 November 1973.

The Ministry of Home Affairs set up a Prisons Re-Organisation Committee to review the system of rehabilitation, industrial training and work discipline. A new system of classification was then adopted in which inmates were grouped into 16 classes under three broad categories.

On 1 January 1988, Tee Tua Ba took over Quek as Director of Prisons. Quek remained as an advisor to the Singapore Prison Service while serving as chief executive officer of the Singapore Corporation of Rehabilitative Enterprises (SCORE), which is now known as Yellow Ribbon Singapore.

When Tee was posted to the Singapore Police Force as Commissioner of Police on 1 July 1992, Poh Geok Ek took over as Director of Prisons and served until his retirement on 1 November 1998, after which he was succeeded by Chua Chin Kiat.

On 23 April 1994, Tanah Merah Prison and Changi Women's Prison were officially opened by Minister for Home Affairs Wong Kan Seng. On 31 December 1999, at the groundbreaking ceremony for the redevelopment of Changi Prison Complex, Wong also unveiled the new vision and revised mission for the Singapore Prison Service, together with the service's tagline "Captain of Lives".

2000–present

Changi Prison's main building (built in 2000)

On 3 January 2000, Kaki Bukit Centre was established as a prison school for inmates' education and skills learning. Teaching resources were centralised and more inmates were able to pursue further education.

In the present-day, Changi Prison Complex houses the most serious offenders in the country, including those serving long sentences (including life imprisonment) and those who have been sentenced to death. The prison complex serves as the detention centre for death row inmates before they are executed by long-drop hanging, which traditionally takes place on a Friday morning. Corporal punishment, in the form of caning, is also carried out twice a week in the prison complex.

The Yellow Ribbon Project, formerly the Singapore Corporation of Rehabilitative Enterprises, was renamed and launched on 2 October 2004 to raise public awareness and acceptance towards ex-offenders and support their re-integration into society.

On 1 November 2007, Ng Joo Hee succeeded Chua Chin Kiat as Director of Prisons after the latter left to serve as the executive director of Aetos Security Management. In the same year, Selarang Park Prison was also transformed to a community supervision centre to manage inmates on community-based programmes and released on supervision.

After two years as Director of Prisons, Ng was transferred to the Singapore Police Force to serve as Commissioner of Police. On 1 January 2010, Soh Wai Wah took over office as Director of Prisons. During his tenure, Soh oversaw the opening of Cluster B in Changi Prison Complex on 20 January 2010. The title "Director of Prisons" was also changed to "Commissioner of Prisons" during this time.

On 10 December 2012, it was announced that a new prison headquarters for Changi Prison Complex would be constructed by December 2014 at a cost of S$118.5 million. The project was awarded to Sembawang Engineers and Constructors, which is owned by Indian EPC company Punj Lloyd. After its construction, the prison headquarters has four main buildings and several smaller ancillary buildings for office facilities, a multi-purpose hall, a club house and an auditorium. It is also located closer to Clusters A and B within the prison complex.

In October 2016, Desmond Chin replaced Soh as Commissioner of Prisons. During Chin's tenure, the Singapore Prison Service obtained the Singapore Quality Award in 2019. Chin also oversaw various initiatives under the service's 2025 transformation plans, including the "Prisons Without Guards" programme which uses technology to automate mundane and routine tasks, as well as the "Prisons Without Walls" programmes which allows more inmates to be supervised in the community and support their reintegration into society.

On 28 September 2020, Shie Yong Lee succeeded Chin as Commissioner of Prisons, becoming the first woman to take up this role in Singapore.

CARE Network

The Community Action for the Rehabilitation of Ex-Offenders (CARE) Network was formed in May 2000 to coordinate and to improve the effectiveness of various agencies engaging in rehabilitative works for ex-offenders in Singapore.

The CARE Network is the first formal structure that brings together key community and government agencies to promote seamless in-care to aftercare support for ex-offenders. The network consists of eight major community and government organisations responsible for the rehabilitation of ex-offenders.

Community-Based Programmes

Overseen by the Community Operations Command (COMC), Community-Based Programmes represent a step-down approach to help offenders make a seamless transition from incare to aftercare by allowing them to serve the tail-end of their sentences in the community. These include the Home Detention Scheme, Halfway House Scheme and Work Release Scheme, where offenders are supervised and counselled by officers from different community and government agencies. In 2018, there were 1,098 inmates on Community-Based Programmes, an increase of 15.4% from the previous year.

Technology

In 2017, the Singapore Prison Service announced its Prison Without Guards transformation plan, which uses technology to enhance operational capabilities and enable prison officers to take up higher order jobs.

Rolled out to all institutions in October 2015, iKiosk has multiple functions that allow inmates to perform self-service tasks. This includes submitting administrative requests (for example, asking for extra letter-writing materials), checking the status of these requests and redeeming privileges.

Launched as part of a pilot project in 2017 in Changi Prison Complex, the Digital Rehabilitation Records Management System automatically tracks inmate activities and attendance records through near field communications technology embedded within inmates’ wrist tags. Inmates can also make purchases by scanning their wrist tags at self-service vending machines.

The Millimetre Wave Body Scanner is designed to screen and detect hidden or contraband objects under inmates' clothing and reduce the reliance on physical searches.

Avatar, launched in 2018, is a human behaviour detection system that uses facial recognition technology and video analytics to recognise aggression and detect abnormal activities in the cell. The system triggers an alert within 15 to 30 seconds of detecting such actions, which could include violence, fighting or suicide attempts.

The Digitisation of Inmate Rehabilitation and Corrections Tool (DIRECT), launched in 2019, provides inmates with shared tablets that allow them to access apps such as e-books, e-news, e-letters and e-learning to support them in their rehabilitation.

Equipment

Although the Singapore Prison Service officers are armed with less-than-lethal weapons such as the Monadnock PR-24 side handle baton/knightstick (more commonly known as the T-baton) and pepper spray while on duty, they are trained in firearms, which may be issued depending on the circumstances.
