A playground in Northwest Omaha has been vandalized with offensive, threatening and vulgar graffiti.

It happened in the Cedar Brook neighborhood just north of Fort Street near Standing Bear Lake.

A slide was defaced with a giant image of male genitalia. Another slide was painted with obscene language. There was also an offensive message left behind for president-elect Donald Trump.

Some of the most disturbing graffiti, however, made direct references to terrorism. The culprits painted "All Hail Osama," as well as "ISIS" and "bomb."

Zach Parker discovered the vandalism Wednesday morning. He lives across the street and often brings his young daughter to the playground. He told WOWT 6 News: "I just don't get it. I'm out of words on why this would happen."

The park is outside Omaha city limits, so city officials tell WOWT 6 News it's up to the neighborhood homeowners to remove the graffiti.

Due to the terrorism-related messages, WOWT 6 News immediately reported this incident to Omaha Police.
