Maryland State Police are asking the public to help identify an armed man who robbed a bank while dressed as construction worker.

Police said the man walked into a BB&T bank, in Fallston, Md., north of Baltimore, on the morning of Nov. 5, wearing a white hard hat, yellow and orange safety vest, and carrying a black duffel bag. From the bag, the man pulled out a black “bull pub” style shotgun, police said, and demanded money and told the employees and customers to get on the floor.
