Prince William County police are asking the public to help solve a pair of Woodbridge convenience store robberies that might be related.

About 11:30 p.m. Wednesday, a gunman robbed the 7-Eleven at 14797 Darbydale Ave., then met a man in the parking lot and both men fled on foot. Fifteen minutes later, a gunman tried to rob a 7-Eleven at 14820 Cloverdale Road.

Both men involved in the first robbery were described as between 18 and 25 years old, 5-foot-11 and 165 pounds. One of the men wore a black zip-up hooded sweatshirt, black scarf, black-and-white shoes and striped gloves. The other wore a black hooded sweatshirt and white shoes.
