An unknown number of chimpanzees escaped their usual living area inside the Kansas City Zoo on Thursday, sending staff and visitors into a bit of a panic. The chimps have since returned to their usual habitat. 

The Kansas City Star reported "more than one" chimpanzee escaped Thursday afternoon, and roamed in a "behind-the-scenes" area of the zoo, away from the visitors who were locked away safely. “As a precaution we have all of our visitors in locked buildings, in safety areas,” zoo spokesperson Julie Neemeyer told the Star. Local news outlet KSHB-41 reports the Africa exhibit was last inspected in 2012, citing USDA information. The exhibit housed 14 chimpanzees at the time. 

No one knows how the chimpanzees escaped, but intrepid local news choppers kept a dutiful eye on the zoo as the chimps enjoyed their new found freedom: 

Zoo officials are investigating the escape as we speak. The zoo is now closed for the evening.
