A Berkeley school district spokeswoman contacted for comment Wednesday afternoon said a statement on the case was coming. Police said investigators with the department’s youth services unit interviewed witnesses and reviewed evidence before getting a warrant for the boy’s arrest, while others at the department worked with school district staff to share necessary information. Officers then got a warrant to search his home, where they found knives, parts for explosives and assault rifles and electronic items police said could be used to make weapons, and reached out to the city’s mobile crisis team to evaluate him. In a statement Wednesday, police said officers received a tip May 21 about the boy’s effort to recruit other teens in a shooting that would include explosives.
