An antisemitic sign targeting Jews at Yale University was found on a street in New Haven, Conn., NBC reported on Monday.

Dr. Gary Plotke discovered the sign hanging on a pole on Chapel Street earlier this month. The sign — reading “YALE IS A JEW HOLE — LET’S ROUND THEM UP!!!” — was posted near Yale-New Haven Hospital.

Dr. Plotke photographed the sign before tearing it down and reporting it to Yale police. The New Haven resident, who has lived in the area for 30 years, said he has never encountered such an antisemitic display before.

“I saw it for what it was: a patently offensive, antisemitic sign,” Dr. Plotke said. “Obviously, I know about antisemitism, but I’ve never actually come face-to-face with a sign like that.”

Plotke also notified the Anti-Defamation League and the New Haven Jewish Federation about the sign, NBC reported. However, he does not expect the person behind it to be caught.

“The important thing is they are aware it occurred and they’ll be more vigilant,” he said, “I think it is not just the question of antisemitism, but any kind of bigoted statement or activities have to be noted and opposed.”

Yale University’s Office of Public Affairs said in a statement that they were notified about the sign on Oct. 4 via a feedback option on their website. They called the sign “hateful and despicable.”

Yale University Press Secretary Thomas Conroy said although the sign was not on school grounds, Yale officials arrived at the scene where the sign was posted and thanked the person who told them about the antisemitic display.

This was not the first public expression of antisemitism aimed at Yale. Last year, students at the prestigious university discovered swastikas spray-painted on the sidewalk outside a freshman dormitory; and in a separate incident, swastikas were drawn on message boards at a different dorm.
