[Columbia, SC] - This morning, at 9:25am, one of the gorillas broke containment at Riverbanks Zoo.  Consistent with our safety protocols, the 325 guests visiting at the time were immediately escorted either out of the Zoo or into secure indoor buildings because public health and safety are our top priority.  Within five minutes, the gorilla was contained safely back in its exhibit.  Within 45 minutes, the Zoo was back in operation with business as usual. By this afternoon there were more than 2,000 visitors enjoying the park.  The gorillas are fine; although during the incident, one food service employee at the Zoo experienced minor injuries.  This employee was treated and released from the hospital several hours later.
