FBI Releases Video of 'Black Hat Bandits' Robbing Bank

They have robbed 7 banks in less than 2 months.

The video released today shows the two robbing a bank in Arnold, Maryland, on January 30, the FBI said.

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.
