SILVER SPRING, Md. (WJLA) -- The FBI and Montgomery County Police are offering a $5,000 reward for the capture of a robber who threatened to bomb a pair of Silver Spring banks.
The midday bank robberies and bomb threats targeted two Capital One branches: 12293 Tech Road on June 10 and 115 University Boulevard West on July 2.
Authorities say the man showed bank tellers devices he claimed were bombs, and said he would blow up their banks if they didn't stuff his bag full of cash. In one instance, he left the 'bomb' behind. The Montgomery County Bomb Squad later determined it to be a fake.
"Oh that's scary," Capital One customer Atchuo Enow said. "Like why would somebody do that?"
"Wow! A bomb is going to harm a lot more people than someone with a gun," Chris Smoot, another Capital One customer added.
Authorities describe the robber as an African American man with a light complexion, about 5'10" to 6'1" tall and 160 pounds. He wore a blue baseball cap and black ski mask in the June 10 robbery, and a sky blue bandanna, fake nose, costume black beard and sunglasses in the July 2 robbery.
Investigators say the man successfully completed each heist in around one minute. They're concerned he's gaining confidence and could become more aggressive in his approach.
Authorities ask anyone who recognizes the man (watch surveillance video above) to call the Montgomery County Police Department at 301-279-8000 or the Baltimore Division of the FBI at 410-265-8080.
"I don't even know where to start. These days people are terrible, you can trust no one," Enow concluded.
