A Charlestown man with a lengthy criminal history was arrested for allegedly robbing a Cambridge Savings Bank branch in Thompson Square late Thursday morning, officials said.
Robert Brady, 40, was arrested in Charlestown shortly after he allegedly robbed the branch at 11:21 a.m.
He was charged with armed bank robbery and making threats. Arraignment information was not available Thursday night.
The robber stole a “small sum of money,” said Wayne Patenaude, the president and CEO of Cambridge Savings Bank, which is headquartered in Cambridge. He declined to divulge the exact circumstances of the robbery or how much money was taken.
“I was happy to report that our employees did an excellent job following our robbery protocol,” Patenaude said.
No one was injured in the robbery, he said. Officials said the money was recovered.
During the robbery, Brady made verbal demands in the bank, and made a threat , said Boston police Sergeant John Boyle, a department spokesman.
Boyle declined to get into the specifics of the threat. He made off with an undisclosed amount of money , said Boyle.
Brady did not have a gun, but is facing an armed robbery charge because of statements he made during the incident, said Boyle.
Boyle declined to detail those statements.
A GPS tracker was embedded in the money that Brady allegedly stole, and police tracked the device to an area in Charlestown, where a man later identified as Brady was seen crossing Walker Street, near Edwards Middle School, said Boyle.
Brady was observed checking over his shoulder continuously, and when he saw a police officer he broke into a sprint, said Boyle. He stopped running at the end of a driveway on Eden Street, where he was arrested. Cash was recovered off him at the time of his arrest, said Boyle.
At the bank, employees met privately early Thursday afternoon. Police had left the scene by 1 p.m.
“We’re really proud of our employees and how they handled themselves under a really traumatic experience,” Patenaude said.
Ken Hall said he was in the area when he saw a large number of police cars shortly after the robbery.
“I came around the corner when it just happened,” he said. “[Police] were just flying around Charlestown and getting him cornered.”
Brady has a criminal history dating back to the late 1990s, according to news reports and court filings. Prosecutors believed he had information about the 1996 murder of a guard and armored car robbery in Somerville’s Twin Cities Plaza, but Brady refused to testify before a grand jury, according to a US Court of Appeals filing.
Brady was held in contempt of court in 1998, sentenced to seven years in prison, and fined $125,000.
