Chimps break out of zoo! (Video)

A visitor at the Belfast Zoo in Northern Ireland filmed some chimpanzees attempting a breakout on Saturday. They had propped a fallen tree branch against the enclosure's wall and then climbed to the top.  The branch is already leaning against the wall when the clip starts and you see a couple of chimps making their way to the top. One of them does escape!!!

Good news, it returned later. Hope they move that branch!
