In the world behind bars in Singapore, the acronym “SOP” refers to the Superintendent of Prisons, the authority figure overseeing the correctional facility. Yet, for one inmate in his 60s, “SOP” took on a personal meaning.
He called himself a “son of prison”, a stark reflection of his identity shaped by over 40 years of being in and out of incarceration, says Superintendent (Supt) Samuel Sia of the Singapore Prison Service (SPS), who was tasked to aid in the inmate’s rehabilitation as his senior correctional unit officer.
“He was abusing drugs as a coping mechanism and, after many years in prison, I could sense that he was defeatist about his life,” he says.
The inmate was also estranged from his daughter, having missed her birth and growing-up years. The possibility of reconnecting with her inspired the inmate to change his ways, says Supt Sia.
“Rehabilitating recalcitrant offenders takes a lot of time and effort. You need to find what motivates them,” he adds.
Helping inmates rebuild their lives, restore their fractured relationships and break the cycle of reoffending are key aspects of rehabilitation that make the work of prison officers – or “Captains of Lives”, as SPS calls them – deeply meaningful.

“Rehabilitation is not always smooth sailing, but that’s what makes the results more satisfying and meaningful,” says Supt Sia.
When the inmate’s daughter finally found him and reached out, Supt Sia encouraged him to meet her and stay out of trouble so that he could recoup the many lost years with her. Now in her 40s, the inmate’s daughter was willing to start building their relationship afresh.
“I told him, ‘You have this opportunity now; if you don’t hold on to it, you will lose it forever’.”
Passionate about helping others from a young age, Supt Sia sought a career that would allow him to change the lives of others. A career aptitude test in junior college (JC) initially pointed him to jobs in social services or – like his mother – in education.
However, it was through participating in an experiential learning programme with the Ministry of Home Affairs (MHA) in JC that he discovered his true calling.

The programme took him to prison institutions such as the former Kaki Bukit Centre (Prison School), where he was able to better understand the meaningful roles of prison officers in keeping Singapore safe and secure.
As a teenager with no prior experience of visiting correctional facilities, his impression of prisons was based on what was depicted in Hong Kong crime movies: chaotic, violent and full of prisoners fighting for power. However, a learning visit to a prison showed him a different story. He watched a video of women inmates reuniting with their children during a Mother’s Day event and was moved by SPS’s efforts in helping inmates renew bonds with their families.
“Rehabilitation is not always smooth sailing, but that’s what makes the results more satisfying and meaningful.”

“It was a heartwarming and touching video, and it made me realise that being part of the rehabilitation process was something I really wanted to do,” recalls Supt Sia. He was awarded the Local Merit Scholarship under the MHA Uniformed Scholarship scheme in 2009 to pursue a Bachelor of Business (Human Resource Consulting) at Nanyang Technological University.
The experiential learning programme dispelled his stereotype of prison officers as strict enforcers focused only on maintaining law and order behind bars. Having become a prison officer himself, he is also able to directly impact inmates’ lives by guiding them to the relevant resources and support systems, restoring their dignity and helping to reconcile broken families who have been affected by incarceration.
“A prison sentence is a punishment for a crime committed, but it should also make a difference in the person’s life, where possible,” reflects Supt Sia.

Today, having risen up the ranks to senior assistant director at the rehabilitation management branch at SPS, Supt Sia is in a position where he can make even more of an impact. He works with and supports prison superintendents to review, set and improve rehabilitation policies and processes.
In the case of the inmate in his 60s, encouraging him to rebuild the father-daughter relationship proved to be pivotal in his rehabilitation. After completing his prison sentence, the inmate underwent the Mandatory Aftercare Scheme and was even joined a cycling support group.
“Rehabilitation is not about a complete transformation but we try our best to assist with every step along the way so that they can become better members of society. That is the longer-term and sustainable solution to keep Singapore safe and secure,” he says.
