The Cincinnati Zoo has temporarily closed its gorilla exhibit after a special zoo response team shot and killed a 17-year-old gorilla that grabbed and dragged a four-year-old boy who fell into a moat.
Zoo officials said the boy fell after he climbed through a public barrier at the Gorilla World exhibit on Saturday afternoon.
He was picked up out of the moat and dragged by the gorilla for about 10 minutes.
Authorities said the child, who has not been identified, fell 10 to 12 feet. He was taken to Cincinnati Children's Hospital Medical Center where he is expected to recover. Hospital officials said they couldn't release any information on him.
Zoo director Thane Maynard said the zoo's dangerous animal response team decided the boy was in "a life-threatening situation" and that they needed to put down the 400-pound-plus male gorilla named Harambe.
"They made a tough choice and they made the right choice because they saved that boy's life," Maynard said.
"We are all devastated that this tragic accident resulted in the death of a critically endangered gorilla. This is a huge loss for the zoo family."
He said tranquilising the gorilla wouldn't have knocked it out immediately, leaving the boy in danger.
