Armed police officer spurs lockdown at Princeton

PRINCETON, N.J. (AP) - Princeton University says a police officer with a holstered gun spurred the school to issue a shelter in place order that was soon lifted.

The order came shortly before noon Tuesday after officials with the Ivy League school received reports about a man on campus with a gun. But they soon determined the man was an officer escorting a group of teens on a tour of the university's art museum.

School officials say the officer was wearing a badge but wasn't in uniform. He was carrying the gun in a holster and the weapon was never removed from the holster.

The school says the officer didn't alert museum staff to his presence in advance.

The shelter-in-place order was in effect for about 10 minutes.
