Singapore police arrested 74 people believed to be involved in illegal soccer betting activities, as part of a two-month Interpol joint operation, local media reported Saturday.

The estimated value of the illegal bets collected by the syndicates was believed to total over 5.6 million U.S. dollars, local TV Channel NewsAsia reported.

Besides cash of more than 62,000 US dollars (78,000 Singapore dollars), police also seized computers, laptops, modems, routers, mobile phones, thumb drives and other items believed to be used for illegal betting activities.

Investigations against the 74 suspects are ongoing.

About 300 people were arrested and over 780,000 U.S. dollars was seized in the Interpol operation to combat illegal soccer gambling in Asia linked to organized crime gangs, Channel NewsAsia said.

Singapore police joined forces with those from China (including Hong Kong and Macau), Indonesia, Malaysia and Vietnam.

They made over 200 raids on illegal gambling dens which were estimated to have handled around 85 million U.S. dollars worth of bets.

The operation, codenamed Operation SOGA 4 (Soccer Gambling), covered the final matches of major national football leagues across Europe, the UEFA championships and EURO 2012.

Operation SOGA was first conducted by Interpol in 2007.
