BLOOMINGTON, Minn. - Police in Bloomington say they've arrested a 13-year-old boy after a making a school threat on social media, as other communities try to assure parents they're taking such threats seriously.

Police say the teen's post implied violence at Valley View Middle School in Bloomington, though it is not exactly clear when the post was made. Police add the post appears related to the current social media trend involving photos or videos of clowns intending to threaten or scare people.

According to police, school officials were immediately notified and proper safety procedures were taken by the district.

Police say the boy admitted to posting the threat. He remains at Hennepin County Juvenile Detention Center pending charges.

Bloomington Police say anyone who posts threats via social media could face criminal consequences.

On Wednesday, Hopkins Police investigated allegations of a clown named Kroacky Klown that was making threats to "kill" on a Facebook page of the same name.

Investigators were able to work with Facebook to identify the suspect, who was identified as a 15-year-old girl from Bloomington.

The Edina Public School District sent home a message to parents about a social media post naming Edina High School as the potential target of violence. "While we and the police do not believe it is a credible threat, we continue to take any threat against our students and community seriously. For that reason we will have an increased police presence at our schools today (Friday) as they continue to investigate the situation."

School officials say the creepy clown posts have been mainly on Twitter, and assure parents they are attempting to track down the source of the threats. If identified, that person will be prosecuted.
