The woman's actions caused the animal to lunge at her, but the seven-year-old Sumatran tiger remained behind a second fence and the woman climbed back out of the enclosure unharmed, the video showed.

A spokeswoman for the zoo, a sprawling forested park that features thousands of animals, said the zoo was unaware of the incident until the video surfaced and is investigating.

"My understanding is it happened Saturday afternoon," zoo spokeswoman Jennifer Tracey said.

Ms Tracey said it was not unusual for items to fall into animal enclosures, but she urged people to contact zoo staff because they had the equipment to safely retrieve lost items.

"No need to go after them yourself. Follow the signs, there is a reason they are there," she said.
