Narrative:

After arriving and completing the shutdown checklist I stepped out on the airstair to see if the chocks were in. I thought the chocks were installed and told the first officer to release the brakes and the aircraft started to roll. The aircraft rolled about 6 feet; a flight attendant and myself screamed to the first officer to set the brakes and he did. No one was hurt and no damage was done to the aircraft.
