The threat that prompted the Los Angeles Unified School District to shut down its schools on Tuesday involved explosive devices, Los Angeles Police Chief Charlie Beck said during a press conference.
According to Beck, the email containing the threat “was very specific to Los Angeles Unified School District campuses and it involved all of them.”
Beck told reporters that the implied threat involved explosive devices, while the specific threat was attack with assault rifles and machine pistols.
Los Angeles mayor Eric Garcetti added that the threats indicated violence and weapons, and that “things were already in place to bring that violence about.”
