Hundreds of rabbits have been released from captivity at a property outside Geelong.
Police believe the offenders opened an unlocked shed which held about 1200 rabbits in cages on the Anakie property sometime between 6pm on January 10 and 6am on January 11.
Several hundred of the animals were let loose from the Ballan Road business.
Police said many of the rabbits were not familiar with how to survive in the wild. It was expected many would die from dehydration or other factors.
Anyone with information about the incident or who saw anything suspicious in the area is urged to contact Crime Stoppers on 1800 333 000.
