Two juvenile girls have been arrested for making clown-related threats using social media in southeastern Wisconsin, copying dozens of similar incidents across the country.

Milwaukee police say investigators tracked a Facebook threat to a teenager in Kewaskum. She's accused of threatening shootings at five Milwaukee high schools by a person wearing a clown mask.

Kewaskum Police Chief Tom Bishop told WTMJ-TV the teen was arrested for making terrorist threats. Also, a 12-year-old girl in West Bend was arrested for making clown threats by text messaging.

Other police departments in Wisconsin and other states have received reports of the so-called `creepy clown' threats. Authorities say in most cases, they're forced to take them seriously as a potential threat to public safety, particularly at schools.
