Cadillac Police say a 13-year-old male student made the bomb threat that brought police to Cadillac Junior High School Friday.
The school will be taking action against the student and Cadillac Police have cited the student in Wexford County Probate Court.
The student was turned over to his fathers' custody.
Four different K-9 teams were brought in to sweep the school but nothing was found and police say there is no evidence that the threat was real.
The threat was found on a bathroom wall Friday afternoon at the Junior/High School complex dated for Saturday, May 3.
Police still do not know the motive of the student for making the threat.
No other arrests are expected.
