San Antonio Animal Care Services said the large tortoise, dubbed Walter O'Hare by rescuers, was found by a group of visitors to Phil Hardberger Park and animal care officers responded to the scene.

The tortoise was taken to Wildlife Rescue & Rehabilitation Inc. in Kendalia. Investigators said they believe the tortoise was a pet that escaped from its home or was abandoned by its owner.
