Narrative:

As of the time the aircraft door closed we had not been catered. I restocked the carts with the supplies we had. The boarding door was closed and all doors had been armed using proper procedures for monitor and challenge. We were waiting to be deiced. I left my door to retrieve my demo equipment (in the last overhead bin aircraft left.) I heard a knock at the door and saw the caterer looking through the window. I crossed my wrists to motion that the door was not safe to open. The door handle began to rise and I grabbed the handle pushing it to the closed position; hoping to signal him to discontinue opening the door. He continued to open the door and I was screaming and banging on the door. (The afa told me she could hear me in the front of the aircraft!) he discontinued opening the door and the inside handle was at a half-way position. I called the flight deck to advise them of the situation and I was told not to touch the door. They would call maintenance. The catering truck pulled away from the aircraft.after several minutes; I went to the flight deck to communicate with the captain the details of this incident. I was at the doorway to the flight deck when the dreaded 'hissing' of the slide could be heard throughout the airplane. I returned to my door to find the catering truck parked at the 2L door and the ripped remains of the slide caught on the ramp of the truck.
