Ang Soon Tong
Ang Soon Tong is a secret society based in Singapore and Malaysia. According to a former police officer, the society was active as early as the 1950s, mainly in the Sembawang area. In 1998, a 19-year-old youth was arrested for setting up a website dedicated to the society.
As recently as 2020, Ang Soon Tong is still active, with one of its members sentenced to reformative probation that year for clashing with members of another secret society.
