A female Bornean orangutan managed to get on top of the outdoor wall surrounding the ape exhibit at the Kansas City Zoo on Sunday afternoon.

The animal quickly re-entered the exhibit and did not have contact with zoo visitors. The zoo activated a Code Red and instructed visitors to stay indoors until the situation was resolved. The Code Red was lifted about a half-hour later.

There were no injuries to animals or people, said zoo spokeswoman Julie Neemeyer.

The orangutan involved was a 7-year-old named Kalijon. She did not have to be tranquilized.
