Dealers in northern Australia are using snakes and crocodiles to guard their drugs, Queensland officials said Monday. Department of Environment and Heritage Protection (EHP) head Michael Joyce confirmed reports that as often as once a week police call in rangers to deal with reptiles being used as sentinels for secret drug stashes in cages and other enclosures, according to a report of DPA. "The role of EHP wildlife officers in rescuing wildlife that may be associated with criminal activities represents just one of the many wildlife issues rangers deal with," he said. The reptiles are placed with the drugs to deter thieves and foil police.
