BELFAST, UNITED KINGDOM — The Belfast Telegraph reports that a couple of naughty chimps broke out of their enclosure at the Belfast Zoo and scared the bejesus out of several visitors.<br /><br />The clever primates staged the escape in broad daylight, using a tree branch as a makeshift ladder to scale the high walls of their enclosure.<br /><br />While most chose to just hang out on the enclosure walls, at least one mischievous monkey was spotted sauntering outside, to the shock of zoo goers.<br /><br />Luckily, the animals were quite chill, and didn't get aggressive with anyone.<br /><br />Belfast Zoo manager Alyne Cairns told the BBC the chimps were "quite cowardly " and knew they weren't supposed to be out. <br /><br />"The cheeky chimps went back into their enclosures themselves, and were later locked in the inner enclosure for their shenanigans.<br /><br />According to The Guardian, zookeepers believe trees in the chimpanzee enclosure had been weakened by recent storms, which made it easier for the animals to break them off.<br /><br />The chimps may have taken pointers from Amber the red panda cub, who snuck out last month following an electric fence failure. She was eventually found in a garden less than a mile from the zoo.
