The bank robber got away … for a few minutes, anyway, according to the police report of a Wednesday incident.

The Cambridge Trust Bank at 1336 Massachusetts Ave. was robbed at 12:12 p.m. Wednesday by a white man wearing dark sunglasses, dark blue hat and blue windbreaker who walked in, approached the teller and demanded cash. Cambridge Police Deputy Superintendent Jack Albert said the man was given some cash and left, going to the lower platform of the Harvard Square T stop, where Cambridge Police officers almost immediately found, identified and arrested him.

Cash taken at the time of the robbery was found on him, Albert said. The suspect is identified as Barry Twomey 48, of Charlestown.

Members of the FBI’s Bank Robbery Task Force were helping with further collection of evidence and information, Albert said.
