Australian police seized 237 million Australian dollars ($246 million) worth of cocaine and methamphetamine found inside a steamroller shipped from China, The Associated Press reported.

Australian Federal Police said Wednesday, Nov 21, that they arrested a Canadian man and a U.S. man in Sydney after finding 350 kilograms (770 pounds) of cocaine and meth. The men were charged with importing drugs and face a maximum of life in prison if convicted.

It was the police agency's second major drug bust in a week. On Friday, police said officials had tracked down a boat carrying 200 kilograms (440 pounds) of cocaine to Australia after it ran aground in the small island nation of Tonga. A corpse was found on board. Officials are trying to determine the cause of death.
