A man dubbed the "bicycle bandit" by the FBI robbed First National Bank in Mount Airy of an undisclosed amount of cash Saturday.
FBI agents said they believe the robber is the same man who has robbed banks in Eldersburg, Timonium and Arbutus since late January.
State police said a man approached a teller at the Mount Airy bank branch at 11:12 a.m., told her he had a gun and demanded "all the 20s and 50s from all the drawers."
Troopers said the teller placed money in a bluish-gray overnight bag that the robber gave her before he ran outside and fled on a bicycle.
No one was injured.
Investigators described the robber as a white man about 5 feet 8 inches tall, between 35 and 40 years old, with reddish-brown hair.
He wore gray pants and a gray and white sweat jacket with a red stripe across the chest, glasses and a sweatband around his head.
Investigators said a neighbor of First National Bank in the 400 block of Ridgeville Blvd. told them a man was riding a bicycle in circles in front of a liquor store about 11 a.m. Saturday, shortly before the robbery.
Minutes later, the man was seen quickly pedaling the bike past the liquor store in the shopping center where the bank branch is located and heading toward the post office.
Police searched the area but didn't find the robber. The FBI said agents believe the robber is the same man who robbed the NationsBank at Carrolltown Center in Eldersburg Feb. 4. The robber in that incident escaped on a bicycle in the snow.
The same bandit is believed responsible for two bank robberies in Baltimore County, at the NationsBank branch in Arbutus Jan. 26 and the First National Bank branch in Timonium Feb. 21.
In each of the Baltimore County robberies, the bandit's picture was captured on the bank camera and he escaped on a bicycle, authorities said. Anyone with information on any of the robberies should call Tfc. Ron Cullison at Westminster state police barracks, 876-8989, or the FBI in Baltimore, 265-8080.
