The global police cooperation agency, which called the operation the "most significant in recent years", said more than 4,000 raids were carried out across China, France, Greece, Italy, Malaysia, Singapore, Thailand and Vietnam during Operation SOGA VI (short for soccer gambling) on dens estimated to have handled $649 million worth of bets.
"The number of seizures is the highest and most significant amongst similar operations in recent years. The SOGA operations are important for tackling not just illegal gambling, but also the organised networks behind this and other types of crime," said Chief Superintendent Chan Lok-wing, Head of Hong Kong's Organised Crime and Triad Bureau.
