School officials say a swastika was found etched on a student's locker at Wilton High School.
A letter was released to parents Monday by Principal Robert O'Donnell. He says the affected locker panel was immediately replaced.
He says the swastika was likely carved into a student locker on Thursday, but wasn't discovered until Monday.
School officials say the student whose locker was targeted is not Jewish. They say they know who's behind it, but they have not released the suspect's name.
