A young man who hinted he had a concealed weapon robbed the Dobbin Center Mobil gas station and convenience store in Columbia just after 10 p.m. Friday night.

Howard County police said the man waited around the store for 30 minutes before confronting the clerk, demanding money and implying he had a weapon.

The clerk opened the cash register and gave the robber an undetermined amount of money. The man then fled.

Police described the suspect as a 6-foot-tall black man in his 20s with a light complexion, wearing a red T-shirt and blue denim shorts.
