A citizen pulled a gun and nabbed one of two men who held up a Mount Pleasant gas station Wednesday night, according to police.

Here’s what happened, according to Mount Pleasant Police Maj. Stan Gragg:

About 7:19 p.m., two men with rags covering their faces walked into the Kangaroo store at the BP station at U.S. Highway 17 and S.C. Highway 41. They showed a gun to a clerk, took an undisclosed amount of money and fired a shot as they left the store.

A passerby with a gun saw what was happening and challenged the two at gunpoint. One man got away, and the other gave up and was arrested when police arrived.

Anyone with information is asked to call the Mount Pleasant Police Department at 884-4176.
