The Madison County Sheriff's Department has made two arrests after a series of bomb threats called in to Sparkman High School.
Two female students were taken into custody Friday afternoon.
Investigators say they tracked them through their cell phones and that the girls have admitted to making at least one of the calls.
These students face charges of making a terrorist threat.
We're told this investigation by no means is over and that the sheriff's department will pursue suspects until all have been arrested.
The names of the students arrested today have not been released.
