Police in southern Utah confirm additional charges are pending against a teenage student accused of bringing a homemade bomb to his high school in St. George.
The unidentified teen was arrested Monday night on weapons-related charges after the discovery of the explosive device sending smoke from a backpack forced an evacuation of Pine View High School.
St. George police say the teen is also a suspect in the raising of the Islamic State group's flag on a pole at another Utah high school in nearby Hurricane last month just after the Florida mass school shooting.
Hurricane Police Officer Ken Thompson told The Associated Press on Tuesday charges are pending related to that incident. He says a search of the teen's home found evidence that ties him to the case at Hurricane High School.
Eds: This version corrects that the teen is accused of bringing a homemade bomb to his school, not that he brought one.
