It was spotted on a day when the community was celebrating academic achievements and good works. 

The Jewish Federation said the symbol was there for days before it was removed. 

"This is my first trip to NC State. We're with a newcomer so, I don't know what's usually here. But, yeah, hatred is what I think when I see that," visitor Angie said. 

University staff said they are still trying to find out who painted it.
