Busy day for police and the FBI: Boston Police tweet that the First Trade Union at 753 E. Broadway was robbed early this afternoon, followed in quick succession by the Hyde Park Savings, 1920 Centre St. in West Roxbury and the Citizens Bank at 696 Centre St. in Jamaica Plain.

That ought to narrow it down.

Or maybe not.

The Daily Free Press reports the University Credit Union, 846 Commonwealth Ave., was held up around noon yesterday, by a black man with a mustache and a gun.

Boston Police tweet the Sovereign Bank at 780 Gallivan Blvd. was held up yesterday afternoon. The robber passed a note, but didn't show a weapon.
