A Dorchester man already behind bars awaiting trial for a Harvard Square bank robbery now faces up to 20 years in federal prison for that and bank robberies in Boston and Brookline.
A federal grand jury last week indicted Jacob Pimentel, 31, on four counts of bank robbery, the US Attorney's office in Boston reports.
In total, the feds charge, Pimentel made off with $6,000 in robberies at the TD Bank branch in Allston on April 25, the TD Bank branch in Brighton on May 4, a Santander Bank branch in Brookline on May 13, and the TD Bank branch in Harvard Square on May 23.
Pimentel's spree allegedly came to an end following the Harvard Square heist when Cambridge Police caught up with him trying to get into a cab outside the Smith Center to flee.
A date has yet to be set for his arraignment in federal court.
