Police raided four residences in the San Fernando Valley and Lompoc Friday and arrested 13 suspected members of a motorcycle gang, seized weapons and uncovered an apparent narcotics laboratory in a garage, authorities said.
The raids were conducted as part of an investigation into the rape and kidnaping of a Northridge woman.
Those arrested in the early morning raids are believed to be members of the Diablos, an "outlaw motorcycle gang" in Southern California with chapters in the Valley, Riverside and Lompoc, said Los Angeles Police Lt. Bob Ruchoft of the Gang Activities Division.
Five women and two men, ages 22 to 43, were arrested on suspicion of conspiracy to manufacture narcotics at a residence in the 7100 block of Sophia Avenue in Van Nuys, where police said they discovered a crude laboratory with chemicals and equipment to produce methamphetamine, a strong stimulant.
About 30 rifles and handguns were taken from the house, along with explosive devices and four pounds of crystallized methamphetamine, police said.
