Six members of the Christian motorcycle gang Set Free Soldiers and three Hells Angels were taken into custody.
The arrests stemmed from an afternoon brawl at Blackie's Bar in Newport Beach on July 27, when investigators say two members of the Hells Angels were stabbed. One member of the Set Free Soldiers was hit with a billiards ball.
Investigators now believe the Christian motorcycle gang plotted the attack on Hells Angels.
"This does appear that maybe this was some type of planned event, but again, we don't know what precipitated or led up to this event, what the motivation is behind it," said Ofcr. Sailor.
Investigators say a number of firearms were seized during the raids. Arrests were made without struggle.
Bail for those charged with attempted murder has been set at $1 million each. The search for five more attempted-murder suspects continues.
