Australian police and animal welfare inspectors are investigating the discovery of at least 55 greyhound carcasses near Bundaberg in Queensland.
The investigation is part of the Joint Greyhound Racing Inquiry Task Force, set up after revelations that Australian greyhounds were being trained to chase live piglets, possums and rabbits tied to mechanical lures.
So far, 36 Queensland trainers have been suspended and six issued with life bans from dog racing.
Queensland Police Minister Jo-Ann Miller said the animal cruelty was totally sickening and it would not be tolerated in her state.
The Queensland Government has also ordered an independent review of the state's greyhound industry to investigate how the practice went undetected.
