He said he was just joking. But he made the threat, he had the gun, and now, he's been arrested.

Less than a week after the tragedy in Florida, a 17 year old Northern Michigan teen has been arrested for making a terrorist threat. Police said he threatened to shoot up a high school in Manistee County, MI.

Police arrested the teen on Monday, February 19th for making the threat which is a felony punishable by up to 20 years in prison. (MLive)

The alleged threat was made verbally last week toward Brethren High School of the Kaleva Norman Dickson School District.

A group of students at the school heard the threat and notified the principal Monday. Deputies from the Manistee County Sheriff's Office made contact with the teen Monday upon being notified.

Police said the teen admitted to making the threat, but said he was "just joking."

Police confiscated the teen's cell phone and an AR-15 from his residence. Manistee County Undersheriff Kenneth Falk said the rifle belongs to the student's parents, who willingly turned it over to police for safekeeping.

The teen was transported to the Manistee County Jail, where he remains in custody pending arraignment. A report has been submitted to the county prosecutor for review.
