Three suspects robbed a Herndon Oil Shell station at gunpoint around 2:40 this morning on Highway 231 just north of the circle.
Three suspects broke into the rear of the building and cut the power before coming in then proceeded to rob the clerk at gunpoint.
Suspects left the scene in what witnesses say was a Ford Explorer.
Police patrols stopped the car and suspects fled on foot near Pontiac Avenue and one suspect were apprehended.
Police are in the process of interviewing that suspect at this point and are currently searching for the rest.
