Waco police Sgt W Patrick Swanton said an uninvited group appeared for the meeting of a loose confederation of biker gangs held Sunday at a restaurant.
One man was injured when a vehicle struck his foot. That caused a dispute that continued inside the restaurant, where fighting and then shooting began, before the melee spilled back outside, Swanton said.
The shootout left nine people dead and 18 wounded. Of the 18 injured, seven remain hospitalized. Swanton described their conditions as stable.
Authorities warned weeks ago of growing animosity between rival motorcycle gangs, a feud that erupted into violence this week at the shootout at a crowded Waco restaurant.
In a memo dated May 1, the Texas Department of Public Safety cautioned authorities about increasing violence between the Bandidos and the Cossacks, Dallas TV station WFAA reported yesterday.
The county sheriff has said all nine people who were killed in the shootout were part of those two groups. About 170 bikers have been charged with engaging in organized crime.
"Traditionally, the Bandidos have been the dominant motorcycle club in Texas, and no other club is allowed to wear the Texas bar without their consent," the bulletin said, according to WFAA.
The bulletin said the FBI had received information that Bandidos had discussed "going to war with Cossacks." It also outlined several recent incidents between the two groups, including one instance in March when about 10 Cossacks forced a Bandido to pull over along a highway near Waco and attacked him with "chains, batons and metal pipes before stealing his motorcycle," WFAA reported.
The Bandidos "constitute a growing criminal threat," the Justice Department said in a report on outlaw motorcycle gangs. The report said the Bandidos are involved in transporting and distributing cocaine and marijuana and in the production and distribution of methamphetamine.
