Police are offering a reward for information regarding recent acts of vandalism and arson against a synagogue in Portland, Oregon.

Scorch marks were discovered Monday on the doors of Congregation Beth Israel in northwest Portland. Anti-Semitic graffiti that read "Die Juden" was scrawled in yellow spray paint against one of its walls.

Rabbi Michael Z. Cahana condemned the vandalism and noted how recently it took place after Holocaust Remembrance Day on April 28.

"It’s easy for us in Portland to think this doesn’t happen around here. That we’re free of antisemitism and hate speech, but the reality is it’s very much a part of our world," Cahana told Oregon Live. "It’s very much of a part of the Pacific Northwest."

Cahana said he does not believe the vandalism is part of a wider plot but urged people to remain cautious.

"But be aware," Cahana said. "And how poignant it is to have this just a few days after having our community’s Holocaust survivors in our sanctuary, where we were honoring their eyewitness, their experience. It really recommits us to being vigilant against antisemitism."
