A silverback gorilla escaped from an enclosure and injured two people Friday at a Rotterdam zoo, a police spokeswoman said.
Yvette de Rave said it was not yet known how the gorilla got out or how serious the injuries were. "From what I can draw from first reports, (the injuries) aren't serious," she said.
The zoo was being evacuated and the gorilla was believed to have entered a building where he is being isolated, she said.
"This is a place with thin windows, not built to contain a gorilla," she said. "Now someone has to go in there and get him."
Police were working with animal trainers to sedate the escaped ape, she said.
