Australian police and customs officials have seized 820 kg of ecstasy tablets and powder stashed inside a bakery oven, in the country?s biggest ever haul of the drug, police said yesterday.

The ecstasy, known chemically as MDMA and valued at about A$200 million ($150 million), was packed into bags and hidden in the wall and base cavities of the oven, which was air freighted from Germany to Sydney last month.

A customs X-ray revealed suspicious packages and a physical inspection found 62 bags containing about 3 million tablets and 115 kg of powder. Police said two people have been charged in connection with the shipment.

Australian Federal Police Commissioner Mick Keelty said he believed the shipment had probably come from Poland. ?Most of the MDMA we get in Australia is in fact sourced from Europe?, Keelty told the Nine Network.

?In this particular case the air freight came directly from Germany to Australia but we believe the origins are in Poland.? Keelty said 1.5 tonnes of ecstasy had been intercepted by Australian authorities this year.
