Singapore police say they have uncovered assets from a massive money laundering scheme that was busted last month, bringing the total amount of assets seized or frozen to 2.4 billion Singapore dollars ($1.75 billion).

The police had launched further operations related to a group of foreign nationals suspected to be involved in laundering the proceeds of their organized criminal activities, including online gambling, police said in a statement on Wednesday.

The latest operations saw additional assets seized or frozen, with the total estimate growing to SG$2.4 billion ($1.75 billion), police said Wednesday. This included bank accounts with a total estimated value of more than SG$1.127 billion ($824 million) and cash of more than SG$76 million ($55 million).
