Three chimpanzees shot dead after escaping from Swedish zoo.

Three chimpanzees escaped from their enclosure in a Swedish zoo for several hours before being shot dead, according to Swedish media, while a fourth was wounded and a fifth was believed to have returned unharmed to the zoo of its own accord.

“They are very strong animals and absolutely not domesticated,” Daniel Wikdahl, a police spokesman, told the public broadcaster SVT on Wednesday, adding that it had been the zoo’s decision to shoot the four because of the danger to the public.

Journalists who arrived on the scene after the escape at 1pm said police told them to “get back in your car and leave” for their own safety. The daily Dagens Nyheter said seven marksmen were called in, aided by a large number of police and several drones.

Annika Troselius, a spokeswoman for the Furuviksparken zoo near Gävle, 165km (100 miles) north of Stockholm, said the animals had had to be put down because there was not enough tranquiliser to subdue all of them.

“We had vets on scene, but they made the assessment that we didn’t have enough anaesthetic. That’s why we called for the marksmen,” Troselius told TV4. “This whole situation is tragic in every possible way. We take full responsibility.”

Troselius said the zoo believed the fifth chimpanzee had returned of its own volition. “But this is an ongoing event,” she told Dagens Nyheter. “We have to be sure the last chimpanzees are actually in the enclosure, and this must be done with great care.”

The zoo urged urged residents to stay indoors, lock their doors and close their windows. “Chimpanzees are strong animals and have a high risk classification,” Troselius said. “Our staff are not allowed to work in close contact with them.”

Furuviksparken, which is currently closed for the season, has seven chimpanzees and is reportedly the only primate research station in the Nordic region. It said in a statement it did not know how the animals had escaped, but would investigate.

“We are taking this very seriously indeed,” Troselius said. “Safety is very important to us and our first focus is to make sure no one gets hurt. Then of course we will investigate this so that it can never happen again.”
