Guangzhou's Liwan District People's Procuratorate will prosecute 66 suspects on charges of organizing online gambling, Nanfang Daily reported.
The suspects, allegedly from a gambling gang, were arrested during a police crackdown in the country's largest online gambling case last year.
Investigators found the gang illegally opened online casinos and attracted online bets valued at 484.08 billion yuan ($79.08 billion) from March 2008 to April 2013, which brought them illegal earning of 1.86 billion yuan.
