Police from southern Vietnam and Cambodia arrested a northerner on Tuesday for organizing cross-border gambling for at least two years.
Dao Quang Cuong, a native of the norhtern port city of Hai Phong, was found managing a casino in Svay Rieng, Cambodia, which neighbors Vietnam's Tay Ninh Province, according to police reports.
Cuong drew a gun and tried to fire it when officers arrived at the scene for the arrest, but the gun wouldn't go off, police said.
Investigators said the casino allegedly employed around 400 people and that Cuong had illegally arranged for thousands of Vietnamese gamblers to Cambodia over the years.
Police said Cuong earned around 30 percent of the money gamblers lost at the casino.
Vietnam only allows foreigners or overses Vietnamese with foreign passports to gamble at legal and licensed casinos in the coutntry.
Cuong, 47, worked at the Cambodian casino with a fake Lao ID since 2007, said police.
Investigators allegedly discovered he had helped Vietnamese people gamble at casinos and hotel gamerooms in HCMC and Ba Ria-Vung Tau Province three years ago.
Before that, Cuong had served jailtime for managing casinos in Districts 8, 9 and Tan Binh, HCMC.
He had managed the casinos for notorious Vietnamese crime boss Nam Cam, who was executed in 2004 for murder, bribery and organizing gambling.
Organized criminal networks in HCMC are known for their links with gangs in Hai Phong, Cuong's hometown.
