A violent fight between a correction officer and a Rikers Island inmate was captured on surveillance video.
The clip shows the two struggling before the inmate knocks the officer to the ground.
A different angle shows the fight continue into a hallway.
While the officer is out of frame, the inmate throws a garbage can in his direction as two other inmates look on.
The inmate who attacked the officer runs off after that.
It's not clear exactly when the fight happened.
