Surveillance video from a Waco, Texas, shootout between rival biker gangs that left nine people dead has been released.

In the video (above), riders can be seen toting guns, crawling under bar stools and even firing shots. Bartenders and patrons are seen hiding for cover, and a group of bikers is eventually seen walking out with hands above their heads.

Police hope the video provides clues about suspects.

Reports from the May incident say about 150 people were at the Twin Peaks restaurant where the shooting occurred. The restaurant previously heard complaints about the hostile nature of the bikers.

In total there were five biker gangs involved and 18 injuries, in addition to the fatalities.
