PRINCETON, N.J. -- Police say a gun scare at Princeton University began when four teen boys found a toy gun on campus.
The Ivy League campus was locked down for about a half-hour Wednesday after someone reported seeing a male with a handgun.
Princeton Borough Police Officer Garrett Brown says four juveniles were going through items discarded by Princeton students who had recently moved out of dorms. Brown says they found the toy gun.
A witness saw one of the boys stick it in his waistband and thought it was real. Brown says the boys did not realize they were causing an alarm.
The boys are in custody for questioning. It's not clear whether they're going to be charged.
