A road rage shooting on Wednesday resulted in the arrest of a man with suspected bomb-making materials in Boulder, according to the Boulder County Sheriff’s Office.

Deputies said the shooting happened just before 7 a.m. at the intersection of North 75th Street and Heatherwood Drive. The victim called 911 and said a driver shot at his truck as he was passing him. A bullet hole was later found in the victim’s front passenger door, deputies said.

An hour later, deputies found the suspect’s vehicle parked outside a house in the 4600 block of Ipswich Street. The owner of the vehicle admitted to driving in the area during the shooting but denied any involvement, deputies said.
