FBI agents arrest possible serial bank robber

SAUGUS, Mass. (WHDH) -- Federal agents arrested a woman on Monday for a bank robbery committed last month, and there's a chance she could be connected to several other similar crimes.

The FBI arrested Johanna Quish for robbing a Back Bay bank in April, but investigators want to know: is she really a modern day Bonnie without Clyde, responsible for a string of bank heists?

It took the FBI just one tip from the public to arrest Quish Monday afternoon during a traffic stop in Danvers.

They brought her to the Saugus Police Department where she was held until her court hearing Tuesday morning.

But the FBI's violent crimes task force is looking to see if a woman wearing a fedora pictured robbing a Dorchester bank in late April is also Quish.

They also are investigating if she is the same woman hitting three banks in one day last Friday.

At 8:25a.m., the woman in the fedora and glasses robbed a Dorchester bank, then at 11 a.m. she tried to rob a bank in Jamaica Plain, only to be told “no” by the teller.

Thirty minutes later, a woman wearing a cap and scarf tried to rob a Dorchester Credit Union.

The FBI would only say the 45-year-old is being charged in the robbery of the Sovereign Bank in the Back Bay with an investigation to see if she's the woman behind the recent spree.
