Story highlights

The boy was taken to a hospital, CNN affiliate WKRC said

Zoo officials say a tranquilizer would have acted too slowly

(CNN) —  

The Cincinnati Zoo shot and killed a western lowland gorilla on Saturday after a 4-year-old boy slipped into the animal’s enclosure, a zoo official said at a news conference.

Harambe, a 17-year-old, 400-pound gorilla, carried the boy around its habitat for about 10 minutes in what the zoo’s dangerous animal response team considered a life-threatening situation, Cincinnati Zoo Director Thane Maynard said at a press briefing.

After the gorilla was shot with a rifle, the child was taken to Cincinnati Children’s Hospital with non-life-threatening injuries, CNN affiliate WKRC reported.

Maynard said it appeared the boy went under the rail, through wires and over the moat wall.

Lions shot after man jumps into enclosure

Two female gorillas were called out of the habitat, Thane said, but the male gorilla went to the moat, picked up the child and began dragging him around the enclosure.

“The child was not under attack but all sorts of things could happen,” Thane said. “He certainly was at risk.”

Thane said zoo officials decided against shooting Harambe with a tranquilizer because the drug takes effect too slowly.

“You don’t hit him and he falls over,” Thane said. “It takes a few minutes.”

Thane said the zoo security team’s quick response saved the boy’s life but all the zoo employees are devastated at losing a rare species.

The western lowland gorilla is a critically endangered species, according to the World Wildlife Fund’s webpage. In the wild, they can be found in Cameroon, the Central African Republic, the Democratic Republic of Congo and Equatorial Guinea.

Harambe, whose birthday was Friday, was born at the Gladys Porter Zoo in Brownsville, Texas, Thane said. The zoo hoped he would eventually father other gorillas.
