The animal, which was collared, bit a child walking with family near Victoria Overlook on Hurricane Ridge in Olympic National Park Sunday afternoon, according to a news release from the National Park Service.

The child was transported by medical helicopter to a hospital in Seattle, according to the National Park Service.

Immediately after the attack, rangers and a canine team began searching for the mountain lion. Staff located the animal that same day and killed the animal the next morning.

There is no threat to the public, and the attack is under investigation, the National Park Service noted.

"Rangers are still gathering details about the incident," a spokesperson for the National Park Service told Fox News Digital in an email, adding links to information about cougar safety.

Last summer, a 5-year-old boy was hospitalized with serious but non-life-threatening injuries after a mountain lion attack in Southern California. The big cat was later euthanized by California state rangers.

Clallam 2 Fire-Rescue, which also responded to the incident in Washington, did not immediately respond to Fox News Digital's request for comment.
