A four-year old boy was seriously injured and hospitalised after he fell into a moat at the Cincinnati Zoo’s gorilla enclosure. The video of the incident is going viral on social media. The toddler is believed to have crawled through a public barrier into the Gorilla’s enclosure. The incident took place at 4 PM on Saturday.

According to reports, the boy crawled through a barrier and fell an estimated 10 to 12 feet into the moat surrounding the habitat. However the child didn’t suffer serious injuries due to fall. But the eye-witnesses saw the gorilla dragging the child violently. The 17-year-old, 400-pound male lowland gorilla, Harambe was seen standing over the kid. He grabbed the boy and dragged him around.

It took almost ten minutes zoo’s dangerous animal response team to arrive at the spot who shot down the gorilla in order to save the boy. When the gorilla was hot the boy was in between the animal’s legs. The authorities decided to kill the gorilla rather than using tranquilliser because it would not have effect immediately on the agitated animal.

“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 and the gorilla population worldwide,” said Cincinnati Zoo President Thane Maynard. “So a beautiful, innocent gorilla has to die because neglectful parents can’t control their kids? Mankind sucks,” a Twitter user wrote.
