“We are thankful that this unfortunate situation has been quickly resolved, an arrest has been made, and there is no longer any threat to Brookfield Zoo. We want to thank again our neighboring jurisdictions that quickly responded to the incident last evening and assisted the Brookfield Zoo Police Department in ensuring that all our guests, staff, and animals were safe,” said Chief Mike Pendola, chief of police for the Chicago Zoological Society, which manages Brookfield Zoo.
