The Catholic organisations that were named by the government as having been used by Cheng to further the Marxist cause included the Justice and Peace Commission (of which Cheng was the executive secretary), the Student Christian Movement of Singapore, the Young Christian Workers Movement and the Catholic Welfare Centre, which assisted foreign workers and maids working in Singapore. The government also said that the detainees had links with Filipino leftists and advocates of liberation theology as well as Sri Lankan separatists.
