Recorded after leaving the cage chimpanzee

Chimpanzee briefly got out of his Cabinet in Dallas ZooOfficials said she did not come into contact with the publicThey are investigating how she may have gotten loose

(CNN) --Dallas authorities responded to a hairy situation in the City Zoo on Tuesday when a chimpanzee escaped from its cage.

Koko, a chimpanzee of 25 years was born and raised in the Dallas Zoo, wandered out of his cage in the main house of chimpanzee, who is confined, the officials said.

A "red code" was called at 10: 15 a.m. CT veterinary and police rushed to the scene.

Koko was shot with a DART tranquilizer and led to their neighborhoods, where she was examined, said Lynn Kramer, Deputy director of the Zoo.

"Koko is stunned but doing well," said Kramer. "Our staff was never in any danger and the public was never in contact with it." "She never left the House of chimpanzee."

The zoo has launched an investigation into how Koko got loose - if it was due to human error or defective cage door, said Kramer. The situation was resolved in 45 minutes, he said.

This is not the first time that an animal has attempted to escape. Last year, CNN affiliate, WFAA reported that a 380-pound gorilla escaped from its cage at the Dallas Zoo. This incident also wrapped safely and within an hour.

In 2004, a male Gorilla escaped from his Cabinet and attacked three people. He was shot and killed, said WFAA.
