Vandals have been spray painting bridges, signs, and streets north of auburn between Kilburn and Central.
But public property is not the only target. Just a few days ago the entire wall of a house was covered with gang signs. Neighbors are getting fed up.
Deborah Curry says she's worried it might be part of a gang war for territory. She has seen drug deals in front of her house. And she says the graffiti problem has gotten out of hand in the past few months.
