Narrative:
During the pushback phase; while the aircraft was being pushed back for engine start. I was told to 'set brakes' by the ground crew on headset. I also noticed my wing men marshalling me to stop. I set the brakes. Somehow the tow bar got disconnected from the aircraft while pushing the aircraft back for engine start. The first officer saw that the tug; that was pushing the aircraft back; separated from the aircraft while the aircraft continued to roll back under its own inertia. The aircraft was stopped after the brakes were set; and no damage to the aircraft or other equipment occurred.
