A man shot after a purported road rage altercation in Little Rock has died, authorities said.

Pulaski County Coroner Gerone Hobbs said the man — whose name has not been released — was pronounced dead at UAMS Medical Center. Additional details weren't immediately available.

Little Rock Police Department Sgt. Cassandra Davis said some sort of road rage developed between the shooter and the victim while they drove separate vehicles south on Interstate 30.

The two vehicles both got off at the Sixth Street exit in downtown Little Rock around 1 p.m. and stopped near Ferry Street. One of the drivers got out of his vehicle and was approaching the other when that driver pulled out a handgun and shot him in the chest and shoulder, Davis said.

The shooter was taken into custody and brought to the downtown detective office for questioning.

Shortly after the call went out, the victim was in the street being treated by medics before being loaded into an ambulance.

Davis said it wasn't known yet how the road rage incident started.

The names of the victim and the shooter haven't been released.

Authorities taped off Sixth Street in both directions at Ferry. Several evidence markers were placed in the street, including some near a piece of clothing, while crime scene officers photographed the scene.
