Ho Chi Minh police said they have questioned a total of 76 people and charged 65 suspects over the alleged drug ring. This includes four Singaporeans, according to media outlet Dan Tri.
Earlier on July 23, Oh's family and friends had made online appeals for information on his whereabouts, saying that he had gone missing after travelling to Vietnam.
The posts said Oh left Singapore on July 16, and that he was supposed to return two days later. The Singapore Embassy in Ho Chi Minh City said Oh had an entry record on July 17.
