Police in the city of Waco, Texas are appealing for calm among rival biker gangs.
This comes amid reported threats among the rival groups following a bloody melee this weekend in the city which left 9 people dead and 18 others in hospital.
Waco Police Sergeant Patrick Swanson admits they are anticipating more violence.
"I will tell you that in the gang world and in the biker world that violence usually condones more violence. Is this over? Most likely not. We would like it to be. We would ask there to be some type of truce between whatever motorcycle gangs are involved. We would encourage them to try to be a little peaceful and let the bloodshed stop."
A meeting among several rival biker gangs at a restaurant in Waco on Sunday turned violent after a fist-fight in the restroom spilled into the restaurant and the parking lot.
170 people are facing charges in connection with the massive brawl, which saw the rival gangs attack one-another with guns, knives, brass knuckles, clubs and chains.
