Colling-Harper is charged with criminal defamation, disorderly conduct and public nuisance.
Police searched Facebook to see who posted a photo of the sign first, and found a woman posted it with the caption, "Seems like Arby's hiring in bc (Brooklyn Center)," WCCO reported.
Investigators contacted the woman, who said Colling-Harper — her boyfriend — was the culprit, and he did it because he thought it was funny, the television station reported.
The manager of the Arby's told police they had to unplug the business's phones because of the volume of complaints and threats, WCCO reported. The manager also said people were yelling at workers as they used the drive-thru, the television station reported.
