A 15-year-old Hoover student has been charged with criminal possession of explosives after police recovered a homemade bomb in his house, according to Assistant Police Chief A.C. Roper.

Police decided to search the boy&8217;s residence after a student at Crossroads Alternative School turned in a threatening note that contained a list of 16 Spain Park High School students, faculty members, two school resource officers and a picture of the explosive.

Roper said police don&8217;t know why the juvenile manufactured the bomb, but he did say the device was nearly complete and made out of common household items. The boy told police that his note was only an expression of anger.

Roper said if completed, the explosive could have been dangerous.

Roper praised students and officials for responding quickly to the threat.

Hoover police contacted the parents of students listed as a safety precaution.

Crossroads Alternative School has both voluntary students and students who are sent there for punishment.

The boy is now in the Jefferson County juvenile court facility. He was expected to go before a Jefferson County juvenile judge on Friday.

Efforts to contact Hoover Interim Superintendent Andy Craig and Hoover School Spokesman Pat Morrow for comment were unsuccessful.
