Princeton University issued an alert late this morning telling students, faculty and staff to shelter in place after school officials received a report that there was a gunman on campus. Law enforcement officials investigated the matter and issued an update shortly after noon assuring people that there is no gunman.
University officials issued the alert after a security guard at the Princeton University Art Museum spotted a man with a gun who turned out to be a police officer. The officer was escorting a tour group.
The police officer, from a jurisdiction outside Mercer County, was with a group of teenagers in an exchange program who were touring the museum’s galleries. The officer, who did not alert Princeton University officials to his presence in advance, was not wearing a uniform but was wearing a badge and had the gun in a holster.
Police officers from the municipality responded and talked with the officer, who was cooperative. The gun was never removed from the holster, officials said.
