After investigations that took nearly one year, police in southern Vietnam Saturday arrested ten people involved in major illegal lottery rings.
They have so far identified 12 big rings of the game called so de, in which the organizers earned between VND50-300 million (US$14,300) a day, said Le Tan Thanh, deputy chief of police in Bac Lieu Province.
So de is an illegal numbers game based on the state lottery, allowing players to bet any amount they want for payoffs up to 80 times the original wager.
Thang said the investigation took such a long time because the rings were well-organized, operated using fax machines and computers, and the houses of the organizers were always guarded.
Bac Lieu Police have called on other ring leaders to give themselves up.
The police last month busted the biggest so de ring in the area, arresting the organizer Tran Thi Lien who gave them many clues that aided their investigation.
