Narrative:

Parked after flight, received chocks signal from ground crew. I released brakes, accomplished parking checklist. We then went to layover hotel. The next day, received word that aircraft had moved about 2 ft during tow bar hook-up for outbound flight. Damage done to aircraft door and/or jetway. That's all we know about it. Aircraft did not move while we were on board.
