Bags with antisemitic messages, unidentified substance found on cars, buildings in Lincoln Park

CHICAGO (WLS) -- Chicago police are investigating after dozens of antisemitic messages were found on cars and buildings.

Not for the first time, Lincoln Park residents woke up on Monday morning to a disturbing discovery: Ziploc bags containing antisemitic messages, in what appears to be a clear escalation, and an unidentified substance that some believe may be rat poison.

"On every doorstep, coming up the street, there were these bags. I picked up a few of them and was horrified to see what they were, and of course, my 4-year-old was, 'Mommy, what is that?' And it just broke my heart. I didn't know what to tell him," said Arden Joy.

Neighbors said they bags were everywhere along Belden Avenue from Geneva Terrace to Clark Street. They were placed on cars, in the parkway and on the stoops of people's homes.
