Ah Kong is a triad with Singapore origins. It is based in Amsterdam and used to control the European drug trade in the 1970s to 1980s. "Ah Kong' which literally mean grandfather, has never been based in Singapore. It is also known to have Malaysian and Thai connections. Most of the members of Ah Kong are Singaporeans and the members continue to speak Hokkien although they were European-based. It was formed when several members of the See Tong (13 group) killed and injured members of their rival gang, Pek Kim Leng (108 group), in a gang clash, and escaped to Holland.
