Another raid happened at the Hells Angels clubhouse in Fresno. Evidence was seized in both places.
"We seized multiple weapons, 10 motorcycles, drugs and garments containing human DNA and blood," said FBI special agent in charge, John Bennett.
"The charges include murder, home invasion, robbery, extortion and witness tampering," said FBI Assistant US attorney, Alex Tse.

The indictment alleges that members of the Hells Angels committed acts of violence to maintain and enhance membership and discipline within the gang, including violence against rival gang members.
Four of the accused face murder conspiracy charges in the killing of an unnamed victim at the Fresno clubhouse in July 2014.
"These individuals used violence and fear for their own personal gain, greed, and power," said Bennett.
