The Dollar General on Wilroy Road was robbed twice in a span of four days, according to Suffolk Police, who believe the same man was involved in both incidents.

The first robbery took place at 9:53 p.m. just as the store was preparing to close Friday, according to a city news release. A man entered the store at 1226 Wilroy Road, showed a firearm and demanded money from the clerk, who was unable to comply and was struck several times by the man before he left on foot, according to the release.

The victim, an unidentified woman, was treated by Suffolk Fire and Rescue personnel for a non-life threatening injury, the release stated. Though no money was taken, it is unclear if any merchandise was stolen, according to the release.

The second robbery happened at about 9:15 p.m. Monday, with a man entering the store and allegedly displaying a firearm before leaving with an undetermined amount of money, according to the release. No one was injured, police said.

Police described the suspect as a black man, about 5-feet-9 inches tall, who was wearing a black windbreaker suit and purple hospital gloves.
