A gorilla has died in the Prague Zoo after accidentally hanging himself with a climbing rope, reports The Huff Post.
Five-year-old Tatu was found dead with the rope around his neck in a sleeping room, said zoo officials.
Zoo spokesman Michal Stastny said all attempts to revive Tatu failed.
According to Daily Mail, another gorilla appeared to be trying to help the stricken animal when staff arrived at the scene.
There were no cameras in the room and it is not clear exactly what happened.
However, mammals curator Pavel Brandl said that Tatu is believed to have unbraided one of the dozens ropes the gorillas use in their pavilion for climbing and put a strand around his neck before hanging himself.
Brandl said: “It was an accident.” He also added that the ropes are checked daily.
Director of Prague Zoo, Miroslav Bobek, said the death was the most tragic event at the zoo since flooding in 2002 killed more than 100 animals.
The zoo still has six gorillas, and they are among the most popular animals there.
Prague Zoo was opened in the Czech Republic in 1931 with the goal to “advance the study of zoology, protect wildlife, and educate the public” in the district of Troja in the north of the city.
It stands on 111 acres and houses about 4,400 animals that represent 670 species from all around the world.
In 2007, Forbes Traveler Magazine listed Prague ZOO among the world’s best zoos.
Tens of thousands of people watched Tatu’s birth online on May 30, 2007.
