Three chimpanzees have been shot dead at a Swedish zoo a day after they escaped their enclosure, with several more still inside the building the animals had taken over.
Swedish officials and media said a fourth wounded chimpanzee had not received veterinary attention because no one could get inside the building at the Furuvik Zoo safely.
The chimps were inside the zoo’s monkey house, but staff have not been able to get another three uninjured ones back into their enclosure, the animal park management said in a statement.
The wounded animal returned to its enclosure on its own.
“This means that we cannot yet allow people to move freely in the park and we are still on full alert,” the zoo said.
The situation is “extremely serious and tragic, both for our animals and our employees,” the animal park said, adding it did not know how the primates got out.
The animals got out of their enclosure on Wednesday local time, prompting the zoo to alert the authorities.
Three chimps were shot dead by local staff, while the fourth was wounded.
The zoo told Swedish media the animals had to be killed because there was not enough tranquilliser for all of them.
“Our focus right now is to get an overview of where the four are now so that we can start working on getting them back to their enclosures in a safe way,” Annika Troselius, a spokeswoman for the group operating the zoo, told Swedish broadcaster SVT. (ABC)
