Police have released surveillance images of the suspect, who they believe has robbed at least four banks in the county since late December. The most recent robbery occurred Monday morning at the M&T Bank branch in the 6300 block of Kirby Road in Clinton. The suspect walked into the bank and passed a note to a teller demanding money, according to police. The suspect fled on foot with an undetermined amount of cash. Police say the same suspect is linked to three previous bank robberies - Feb. 9 at the Capital One Bank branch in the 1000 block of Largo Center Drive in Largo; Jan. 10 at the SunTrust Bank branch in the 5700 block of South East Crain Highway in Upper Marlboro; and Dec. 29 at the Wells Fargo Bank branch in the 5800 block of Silver Hill Road in District Heights. In each incident, police said, the suspect handed a note to a bank teller demanding money and fled on foot. Each note contained a threat to detonate a nuclear weapon. The suspect did not show any visual evidence of such a device, according to police spokesman Cpl. Evan Baxter. Police describe the suspect as a male between 25 and 40 years old. His height is between 5 feet, 9 inches, and 6 feet; he weighs between 150 and 200 pounds, police said.
