Huge Drug Bust Down Under

Australian authorities have seized more than half a billion dollars worth of meth and heroin in Sydney.

Illegal drugs with a street value of half a billion dollars have been seized and seven people arrested in Sydney after a tip-off from US drug agents.

More than half a tonne of drugs, including 306kg of crystal methamphetamine, also known as ice, and 252kg of heroin, were seized in Sydney during the operation.

Seven people - all Hong Kong nationals - have been arrested. They are expected to face Sydney Local Court  later Tuesday.

It is the largest seizure of ice and third-largest heroin haul  in Australian Federal Police history.
