This is Bokito, a gorilla housed in the Rotterdam Zoo, who achieved international fame on May 18, 2007, for escaping his enclosure, attacking a woman, and then going on a smashing spree in a nearby restaurant. He was sedated with a tranquilizer gun and placed back in his enclosure, which is (has been?) to be upgraded to include one-way mirrors for visitor viewing, as opposed to the open windows that had him living in a fishbowl environment.

The woman he attacked had been visiting him on average four times a week, and claimed a special bond with him. She is seen in the video below.

any primatologist will tell you, don't make eye contact with primates: it will see such behavior as a challenge and will make them angry

Despite having been warned by zoo staff to stop antagonizing Bokito, she's now suing the zoo (or was, as of 2007).
