Investigators looking into a bomb threat made against Lakeview School District Tuesday morning led to three teens being detained in Battle Creek.

The Battle Creek Enquirer reports that the threat was discovered through two notes; one left in a bathroom at Lakeview Middle School, and the other left outside the home of a parent. No bomb was found after a search, but classes were cancelled district-wide Tuesday as a precaution.

Investigators at this time believe that the incident stemmed from an argument between two girls at the Middle School, with some kids possibly trying to “set-up” another student.

Three teenagers were taken into custody, and will be facing charges.
