Authorities in northwestern and southwestern Michigan say they have arrested teens accused of making threats against high schools.
Manistee County sheriff's officials say they contacted a teen Monday after learning about the threat to "shoot up" Brethren High School. Officials say he told deputies that he was joking.
Police say they confiscated an AR-15 semi-automatic rifle and a cellphone from his home. He was taken to the county jail, where he awaits arraignment.
The Kalamazoo Gazette reports a student was arrested Tuesday after he was overheard making threats toward Otsego High School. School officials say they don't know whether it's a credible threat but are taking it seriously.
There have been numerous threats in Michigan since a massacre that killed 17 high school students and faculty last week in Florida.
