“I’m happy to report he’s actually up and grumbling and interacting with the rest of his gorilla family,” Malcolm Fitzpatrick, the zoo’s curator of mammals, said. The gorilla’s escape is being investigated by zoo officials. London zoo was placed under lockdown after the event occurred. “At no time were any of our visitors in any danger. The gorilla did not get out of the safe space, there were only about 100 visitors, it was the end of the day and I would like to thank all of those visitors for co-operating and moving in to buildings,” Fitzpatrick explained. A helicopter was used in the operation. Footage posted on social media showed armed police searching the zoo after the animal. The zoo is one of the capital’s most popular tourist spots.
