Yoong Siew Wah

From PoliticalSG

Yoong Siew Wah is a distinguished former Singaporean civil servant known for his significant contributions to the nation's security and governance.

His career spanned several key positions, notably as Director of the Corrupt Practices Investigation Bureau (CPIB) in the 1960s and Director of the Internal Security Department (ISD) from 1971 to 1974.

Early Career and CPIB Leadership

In the 1950s, Yoong began his public service in the Singapore Special Branch, the precursor to the ISD, where he played a pivotal role in countering communist insurgencies. His expertise and dedication led to his appointment as Director of the CPIB in the 1960s, where he was instrumental in combating corruption within the public sector.

Director of Internal Security Department

From 1971 to 1974, Yoong served as Director of the ISD, overseeing national security during a period marked by internal and external threats. His tenure is noted for implementing effective measures against subversion and espionage, contributing to Singapore's stability.

Involvement in the 1961 CIA Incident

In 1961, while serving as an Inspector in the Special Branch, Yoong was approached by the Central Intelligence Agency (CIA) for recruitment as an informant.

With authorization from Prime Minister Lee Kuan Yew, he engaged in a counter-intelligence operation that led to the exposure and arrest of CIA operatives in Singapore.

Yoong’s role in the CIA incident earned him the rare distinction of holding two prestigious medals:

  • The Colonial Police Medal, awarded by the British Queen for his contributions to the Special Branch.
  • The Service Medal, conferred by Lee Kuan Yew’s government for his exploits in the 1961 CIA operation.

Yoong is the only police officer in the history of the Singapore Police Force to hold both medals, a testament to his exceptional service and contributions.

Post-Retirement Activities

After retiring from public service, Yoong remained active in public discourse, often sharing his insights on Singapore's political history and governance. He maintained a blog titled "Singapore Recalcitrant," where he discussed various national issues and reflected on his experiences.


Personal Life

In his 90s, Yoong experienced a personal transformation, embracing Christianity and being baptized at the Cornerstone Community Church on 2 February 2020.

He attributed this change to a profound experience during the 1961 CIA incident, which he interpreted as divine intervention.
