More than 500 horses have been found dead at a property in the NSW Riverina region.
Wagga Wagga City Council, supported by police, investigated reports horses had been butchered at the property and their carcasses left in a dry creek bed.
The council inspected the property and said it became clear the horse slaughtering had been occurring for a long time.
Carcasses were found throughout the property, totalling more than 500 dead horses.
Some were no more than skeletal remains while others had been killed recently.
