TAYLOR, Mich. (AP) — A 15-year-old Detroit-area student has been charged after allegedly threatening a high school security guard and being caught with a gun.

The teen was to appear at a preliminary hearing for carrying a concealed weapon, an intentional threat to commit an act of violence against school employees or school and weapons possession charges, the Wayne County prosecutor’s office said.

He will be prosecuted as a juvenile.

Taylor police officers arrested the teen Wednesday morning at Taylor High School, southwest of Detroit. They were called to the school after the teen was told to return to class and allegedly threatened to shoot a security officer.
