Two banks in Northwest D.C. were robbed Monday morning, and authorities believe the heists were committed by the same woman.

The first robbery occurred at about 9:15 a.m. at a PNC Bank on the 4200 block of Wisconsin Avenue NW in the Tenleytown area. In that incident, the robber walked into the bank, passed the teller a note and obtained money, according to the FBI.

The second robbery took place about 15 minutes later at a Bank of America on the 3400 block of Connecticut Avenue NW in Cleveland Park -- about 1.5 miles away from the PNC branch. In that incident, the woman asked a teller for cash, said that she had a gun and got money.

Authorities were not disclosing the amount of money that was taken from the banks. They said that they were not aware of any injuries in either robbery.

The culprit was described as a female with dark hair who may be Hispanic. She appeared to have a bandage on her nose or lip.

The robber was wearing dark sunglasses, a black puffy coat, black pants, black leather gloves, a black scarf around her head, a black-and-white polka-dot scarf around her neck and white tennis shoes.

Anyone with information can call D.C. police at 202-727-9099 or the FBI at 202-278-2000.

Most bank robbers are men, but there have been multiple female bank robbers in the D.C. area in the past few years, FBI spokesman Andrew Ames said.

"It's not uncommon," he said. "It's not like this is the first one."

In November 2011 a woman dubbed the Blond Bandit committed a series of bank robberies and carjackings in the region. The robber, Stephanie Schwab, was sentenced in August to 11 years in prison.
