Australian police have made their largest-ever seizure of the drug methamphetamine. The drugs, hidden with cleaning chemicals in a shipment from southern China, weighed 1,290 pounds and had an estimated street value of $440 million. A Singapore, Australia and Hong Kong man have been arrested and face a maximum life sentence if found guilty. Police said the seizure followed a four-month investigation triggered by a tip about suspicious activity at a storage facility in Sydney. "That one phone call was the one thread that allowed us to pull and unravel a syndicate that will be stopped forever," New South Wales Police Commissioner Andrew Scipione said.
