BELLINGHAM, Wash. (AP) — Several businesses around Bellingham discovered swastika stickers posted on their windows over the weekend.

One of the owners of Village Books, where stickers were stuck to three of their windows, said they’re going over surveillance video to see if they can spot who put them up.

Brandywine Kitchen also said they were hit with the stickers, which had a swastika and the words “we are everywhere.”

Bellingham’s mayor says police are investigating it as a potential hate crime.
