PRINCETON UNIVERSITY: Alert issued after gun spotted on campus, but local police quickly resolve the issue

By Lea Kahn, Staff Writer
A report of a man carrying a gun on the Princeton University campus turned the school upside down and resulted in a brief lock-down on campus around lunchtime Tuesday.
A security guard at the Princeton University Art Museum saw a man with a gun and alerted authorities, according to the Princeton University Office of Communications. As a result, an alert was issued to people to shelter in place.
The man, who was discovered to be a police officer from a town outside of Mercer County, was escorting a group of teenagers on a tour of the art museum. He was carrying a badge and a gun – which was never removed from its holster – but he was not in uniform.
The Princeton Police Department responded and police officers quickly resolved the issue. They spoke to the out-of-town police officer, who had failed to notify Princeton University officials in advance that he would be on campus.
