Arrests and detentions under the Internal Security Act (ISA) and its predecessors, the Emergency Regulations Ordinance, 1948 and the Preservation of Public Security Ordinance, 1955 (PPSO) have never been collated. Only the government possess a complete record of people arrested, imprisoned or banished.
There is also no record of people who left Singapore because they threatened with arrest under the ISA.
Hansard of February 1963 listed 110 people detained on 2 February 1963 (Operation Cold Store). In the list below, 121 persons were detained on that day. It is not clear if the names in Hansard excluded those arrested, interrogated and released before the issue of a detention order i.e. within 30 days of arrest as permitted by the ISA.
We hope a Truth and Reconciliation Commission will one day determine who and why people were arrested under the ISA.
