Police are looking for three men who reportedly robbed Coastal Gas Station at 2010 Old Bridge Road late Tuesday night, Prince William County police spokesperson Jonathan Perok said. 

"Employees reported to police that three unknown, masked men entered the business and approached the counter," Perok said. "One of the men was armed with a handgun and demanded money. The men took an undisclosed amount of U.S. Currency before fleeing the area on foot."

No one was injured. Police used a K-9 unit in the search, but did not find any suspects.

Police are looking for three black males of unknown ages. The armed suspect was described as 5-foot-9 with a medium build. The second and third suspects were both about 5-foot-10 with thinner builds. All men were described as wearing black jackets, black pants, masks and gloves.
