Go-rilla, Go!

"I saw the beast running through the park with a woman behind him, him grabbing her forearm," De Jonge said.

At a distance of around 30 yards, he saw the gorilla lie down near the woman and then heard her scream. “He bit her, or I think he bit her, because when he stood up his mouth was covered in blood," De Jonge said. He said he then stopped to tell arriving police what had happened and ran with them as they traced the gorilla to a nearby restaurant terrace.

The zoo was packed with visitors as many Dutch took advantage of a national holiday Thursday to make a long weekend. "Everyone was in panic, running away, screaming, wailing, screaming kids running around, I don't know what all, kids without parents -- it was a total drama," De Jonge said. Children cowered in their parents' arms as the gorilla loped past.

People tried to hide inside the restaurant and were trying to bar the door, but fled as the gorilla approached, De Jonge said. Bokito then punched through the glass door and ran inside.

"They were all in panic -- the animal, too, I mean -- and all the people ran outside the restaurant, and zoo personnel were running up and they were able to keep the animal inside by barricading the doors with garden furniture and things," he said.

De Jonge said he later saw the woman "covered in blood," but walking unaided.
