Police in Princeton, N.J., are searching for a man who has been placing stickers displaying anti-Jewish propaganda on various properties across the city. They have asked the public for help in identifying the man, asking anyone with information to come forward.

“The individual is suspected of placing stickers containing antisemitic propaganda on select properties throughout Princeton,” the Princeton Police Department said in a statement on Facebook, along with a photo of the suspect on a bike. “The materials appear to target specific locations and contain messaging intended to intimidate, harass, or promote hatred toward members of the Jewish community.”

The police said that the case is being treated “with the utmost seriousness due to the nature of the materials and their potential impact on our community.”

They described the suspect as a “middle-aged white male, with pepper-gray hair, wearing glasses, a tan shirt, gray shorts, and black sneakers, riding a light-colored mountain bike.”
