Another surveillance camera photo of the robber, who police say pulled out a shotgun inside the bank, was issued late Wednesday night, as investigators stepped up their efforts to identify and find the robber.
As in the two earlier photos issued following the robbery on Monday, the robber wore a white hard hat and safety vest, which made him appear to be a construction worker.
"We hope to be able to determine if this was just a costume or if he was a real construction worker," Sgt. Jeff Kloiber said Thursday morning.
He added state police are tracking down a few leads, but had no suspects in the robbery as of that time.
Anyone with information that can help identify the robber is asked to contact the Bel Air Barrack at 410-879-2101. Information leading to the apprehension of the suspect could be eligible for a reward up to $2,000 from Metro Crime Stoppers, according to information released with the latest surveillance photo.
Maryland State Police were notified of the robbery at the bank branch at 1911
Witnesses told police a man went into the branch, displayed a gun, demanded cash, then fled. No one was injured.
The robber is described as a white man, 5 feet, 10 inches to 6 feet tall with a stocky build. At the time of the robbery, he was wearing a white hard hat, a yellow and orange safety vest, gray sweat shirt and faded blue jeans, according to TFC M. Cornbrooks at the Bel Air Barrack.
The robber went into the branch carrying a clipboard, a water main key and a black duffel bag, out of which he pulled a black shotgun, which State Police later described as a "Bull Pup style shotgun."
The robber demanded cash then told the tellers and customers to get on the floor. He stole an undisclosed amount of cash from the teller's drawers and coin vault and then fled the bank on foot and was last seen traveling north on
Troopers used a police dog and a Maryland State Police Medevac helicopter to search the area, but could not find the robber.
