Boston Police and the FBI are looking for a guy they say has robbed four banks in the Back Bay and the South End over the past month.

He's described as light skinned, between 5'7" and 5'10" and a fan of wearing clear tape on his fingers.

The banks hit: Sovereign Bank, 67 Beacon St., 2/25; Citizens Bank, 560 Comm. Ave, 3/14; Citizens Bank, 607 Boylston St., 3/22; and the Mercantile Bank, 1320 Washington St., 3/25.
