One of those threats allegedly targeted shootings at five Milwaukee high schools by a person wearing a clown mask.
South Division High School student Daquan Elis says he and many classmates received a Facebook message from a fictional clown profile page about serious threats.
"They said they were going to kill me and come up to south,” Elis said.
The teen behind the account threatened shootings this week at Riverside University, Messmer, South Division, John Marshall and Universal Academy for the College Bound.
"I was kind of scared a little,” Ellis said. "I thought they were going to come up here."
Milwaukee police got involved tracking the Facebook profile to a juvenile teenage girl in Kewaskum.
"She called in sick to school,” said Kewaskum Chief Thomas Bishop. "We knew she was home at the time these threats were being posted online."
Bishop said the threats were deemed not credible, however the teen was arrested for making terrorist threats -- a potential felony charge.
“You don’t know if these are going to be carried out or not,” Bishop said.
Also on Monday, a 12-year-old girl was arrested in West Bend for making clown threats via text message.
The creepy clown trend has been an alarming national phenomenon over recent weeks. Local police departments including Milwaukee, Oak Creek, Sheboygan, South Milwaukee and West Bend have either received reports of clown threats over social media or copycat clown sightings.
Some departments said the people behind the masks are crossing the line into nuisance activity.
"For me as a parent it’s real scary,” said parent Nancy Perez.
While parents at South Division are thankful the shooting threat never materialized, some said the creepy clowns trolling the neighborhood also need to stop.
"This is a neighborhood, you’ve got kids around here,” Perez said.
Bishop said suggested charges for the Kewaskum teen await the decision of the Washington County District Attorney.
