The drug haul was reported to be the second largest of its kind in Australian history.

“If it is true, it is embarrassing if it came from Port Klang. How did it go undetected? How did this smuggling activity continue for 12 to 16 times undetected, until the Australian authorities uncovered this?” he said while at an event with the police here.

Anwar has called for Bukit Aman to carry out an urgent investigation and report within the next one or two weeks.

“I want to know what actually happened,” he said.

“How can a sophisticated system not detect the drugs in the consignment? How has this been happening 12 to 16 times (over the years)? We should not compromise with these criminals and we must bring them to book,” Anwar said.

The 336kg consignment of heroin, with a street value of some A$268 million (RM790 million), was seized by Australian federal police in Brisbane, Queensland, on March 13.

The drugs were hidden in two concrete blocks, each weighing about 500kg, marked as solar panel accessories inside a sea freight container, Australian police said. Officers drilled into the concrete blocks and removed 960 packages, each containing about 350g of heroin.

Transport minister Loke Siew Fook said the ministry was identifying and investigating the port responsible for shipping the heroin to Brisbane.
