Thousands of visitors had their day at the Phoenix Zoo cut short by a sudden security scare. Officials say a bomb threat came in at around noon Friday while about 2,000 visitors and 500 staff and volunteers were inside. Everyone was moved out in about 10 minutes, and police found no explosive after sweeping the grounds. Out of an abundance of caution, park rangers also evacuated visitors at Papago Park, which borders the zoo. Zoos in Kentucky and Ohio received similar threats around the same time this weekend. While it's still unclear who is behind the threat, Phoenix Zoo CEO Bert Castro says staff are well trained for these types of emergencies. https://lnkd.in/gM_tQ96t
