PERRY, Iowa (AP) — Investigators are trying to determine who spray painted the words “report illegals” on a sidewalk near where one Iowa town was holding its annual Latino festival. The Des Moines Register reports that the message was found near the high school in Perry, Iowa, on Sunday along with a stenciled phone number for U.S. Immigration and Customs Enforcement. Police painted over the message shortly after it was found.

Perry Police Chief Eric Vaughn says investigators are reviewing surveillance footage from the school to try and identify who painted the message. Immigration lawyer Tim Farmer says the vandalism is unfortunate. He says it’s important for people to get to know immigrants as human beings.
