Sydney Zoo has been turning visitors away after an animal has reportedly escaped.
Visitors have either been locked inside buildings or told to remain in their cars.
Earlier reports incorrectly named Taronga Zoo as the site of the apparent jailbreak.
A spokesperson for the Zoo could not be immediately reached for comment and details are still unclear as the situation is unfolding.
Social media reports that the animal is an app and the zoon has been in lockdown for at least an hour.
In a separate post to the Sydney Zoo Facebook page, staff announced the death of Mogli, “a beloved member of our chimpanzee troupe.”
Mogli was found in the chimpanzee habitat this morning by staff who are currently investigating the circumstances of the incident.
“The team are in a state of deep shock and grief,” the post said.
