— -- The FBI is offering a $30,000 reward to anyone who can help them catch the so-called "Black Hat Bandits."
The pair has robbed seven banks in Virginia and Maryland in the last two months, according to the FBI. They received their name because they don black hats, winter coats, sunglasses, and some kind of facial disguise - like a ski mask or a fake beard - during the robberies.
Their most recent robberies happened on Feb. 18 when they hit two banks within 40 minutes of each other in Virginia.
The robbers have become increasingly violent, the FBI says, "most recently holding a gun to a customer's head and jumping teller counters in attempts to gain access [to] bank vaults."
Based on their tactics, the FBI believes the robbers either have military or police training.
