MacCausland brought the bag and the cash to police heaquarters, in keeping with city law. Police said the passenger called about the missing bag while officers were inspecting it. The man was reunited with the bag after showing proof of ownership.

"This hackney driver exhibited exemplary behavior and his honest deed should be recognized," Boston Police Commissioner William Evans said in a statement. "His actions represent the high standards that our department has for our drivers."

MacCausland received a $100 reward.
