Vietnamese authorities have handed down stiff sentences for those 59 individuals connected with online gambling site M88.com.

On Tuesday, a Ho Chi Minh City court sentenced 52 defendants to lengthy stints in prison, while seven other defendants received suspended sentences. The 59 defendants were caught up in the January 2013 bust of a ring tied to the Philippines-licensed M88, which Vietnamese authorities have dubbed the country’s most popular online betting site.

Amazingly, only six of the accused were agents working on behalf of M88, while the rest were simply gamblers whose names were found in the agents’ files. The agents were convicted of ‘organizing gambling’ and handed sentences ranging from two to seven years along with fines of up to VND 50m (US $2,300). The site’s main agent in Vietnam, Nguyen Vo Hoai Tram, remains at large.

As for those 46 gamblers, they received sentences ranging from one-and-a-half to four years in prison simply for placing wagers. Among those receiving four-year sentences was Dao Ngoc Quy, who wagered VND 8.8b ($404k) on football, losing VND 6b to the site. The gamblers were also fined between VND 5m to 30m apiece.
