Seven banks have been robbed in seven towns over the past few weeks, and a source close to the investigation said authorities believe a single person is behind the crimes.
The most recent robbery occured Thursday at the Liberty Bank in Durham. State police released several surveillance photos of the suspect.
"It's a little crazy," said Middletown resident Kate Tredwell. "You don't hear it all that often that people are hitting up banks day after day."
The crime spree began July 27 in Branford, where a TD Bank was robbed on West Main Street. Police said the suspect got away with an unknown amount of money and alluded to having a weapon, although he did not display one.
Then, on Aug. 12, the suspect targeted a Webster Bank on Highland Avenue in Cheshire. Police said he gave the bank teller a note saying he was holding the bank up and fled with a small amount of cash.
A TD Bank in Berlin was hit the next day. Police said the robber once again handed the teller a note demanding cash. At the time, local police believed the perpetrator in Berlin may have also been responsible for two bank robberies in West Hartford.
He held up a Liberty Bank in Deep River on Aug. 17, then the People's United Bank in Milford on Aug. 19 and a TD Bank on Wells Road in Wethersfield on Aug. 31, according the source.
During many of the holdups, the robber handed over a note demanding cash and warning that he had a weapon. No weapon was ever revealed.
State police said the the Durham robber is in his early to mid-30s, stands approximately 6 feet tall and is thin with an athletic build and some facial hair. He left the area in a green, older-model sedan.
In surveillance footage from each case, the suspect appears to be on the phone and always wears a hat. No one has been injured during any of the robberies.
"Hopefully they catch the guy and this doesn't happen anymore," said Tredwell.
The Connecticut Bankers Reward Association is offering $1,000 for information leading to an arrest in the Durham robbery.
Anyone with information on the bank robberies is asked to call state police.
