Police in Alabama say a 12-year-old boy may face criminal charges because he brought a bomb to school.
It happened at Falkville Elementary, about 40 miles southwest of Huntsville.
The principal of the school says the boy gave the device to another student, and it was later confiscated by a teacher.
Police say the boy said he didn't plan to use the bomb at the school.
They say the bomb was made with three fire crackers taped together with copper wire.
Police say there wasn't a battery attached to the device.
The boy has been suspended from school.
