One man is behind bars, and another is on the run after an armed robbery at a Kangaroo Gas Station in Mount Pleasant.

Police responded to the store at 2846 Highway 17 about 7:20 Wednesday night as two masked men attempted an armed robbery.

As the armed robbers were leaving, a passerby saw what was happening and pulled his own gun, challenging the suspects at gunpoint.

One of the suspects escaped, but the other was taken into custody.
