A 400-pound gorilla escaped from his enclosure and ran amok in a Rotterdam zoo Friday, biting one woman, dragging her around, and causing panic among dozens of visitors before he was finally subdued, officials and a witness said. The Diergaarde Blijdorp zoo was evacuated and the 11-year-old gorilla, named Bokito, was eventually contained in a restaurant within the park, police spokeswoman Yvette de Rave said. Four people were injured, including the woman who was bitten, zoo director Ton Dorrestijn said.
