SIDNEY, Neb. (AP) — A 51-year-old Colorado man is facing explosives charges in western Nebraska.

Nebraska prosecutors say Edgar Almond, of Loveland, Colorado, is charged with unlawful possession of explosives and possession of a destructive device. His attorney declined to comment Friday. Almond’s next court hearing is scheduled for Sept. 27.

Sidney police say his wife reported Wednesday that he’d detonated a bomb in the area the night before and that he had bomb-making materials in his vehicle in front of her house. After he was arrested outside the home, police searched his van. Officers say they found bomb materials inside. A bomb fragment also was found in the area.
