Transit Police are looking for a guy they say has held up the Fresco flower stand on the Dartmouth Street side of Back Bay station twice this week.
The guy made off with cash in afternoon heists on both Monday and Wednesday. On Monday, he motioned as if he had a gun. He's also wanted for possibly menacing other people in the station.
He's described as Hispanic, about 22, 5'8" to 5"10" and thin. He has a tattoo behind one of his ears.
If he looks familiar, contact detectives at 617-222-1050 or send an anonymous tip to 873873.
