A 17-year-old Belfry boy has been arrested on suspicion of making bombs from holiday sparklers.

Carbon County Sheriff Thomas Rieger said callers had complained last week about "large booms" from explosions in town. An investigation led to the youth, who was arrested Saturday. The sheriff declined to identify the boy.

Explosive devices made with tightly taped sparklers can have the force of a quarter-stick of dynamite and are very dangerous, the sheriff said. No injuries from the incidents were reported.

The youth will appear on misdemeanor charges in youth court, Rieger said.
