Francis Eugene Alan Murray was arrested Tuesday on charges of armed robbery and possession of a firearm during the commission of a crime.
According to an incident report, the suspect entered Augusta Metro Treatment Center, 525 Ellis St., about 10:30 a.m. April 25 and demanded cash from employees at gunpoint.
An employee handed over cash drawers to the robber, who was wearing a hoodie and gloves.
A Waynesboro, Ga., man at the facility told police he went to his car to get his firearm after employees screamed about a gun. Before he got back, the robber ran from the building.
The man told police he chased the robber until he jumped into the passenger seat of a black Chevrolet Monte Carlo and got away.
