Prosecutors charged a suspect after a homemade explosive detonated and damaged a clinic in Grand Chute in eastern Wisconsin. WTAQ reports police were holding the suspect on a probation warrant after he was involved in an accident shortly after leaving the scene.

Officials with the Winona County Sheriff's Office tell the Associated Press they are seeking an arrest warrant to take a 17-year-old suspect into custody. Authorities say the teen was at the hospital in Rochester when the pipe bomb was discovered in the trunk of his mother's car last Thursday. It was safely detonated and no was hurt. The teen allegedly made the 3-foot-long pipe bomb in Winona County.

Roads were closed and nearby businesses evacuated while a bomb squad detonated the device in the man's vehicle.
