Ceja was released on $500,000 bail and is due back in court in October. Police believe the fireworks were bought in Nevada and taken to Los Angeles to sell in the neighborhood for use on July 4th. Police arrested resident Arturo Ceja, 26, on suspicion of possessing a destructive device. Those fireworks were detonated at an off-site location. The explosion came after police spent the day disposing of thousands of pounds of commercial-grade fireworks that were found in a South Los Angeles home following an early-morning tip.

Some victims have filed legal claims - the precursor to lawsuits - against the city. The Los Angeles chapter of Black Lives Matter and other organizations want more answers and reparations for residents hurt in the blast. Moore announced the preliminary findings of the investigation during a media briefing. Fireworks are illegal to sell or possess in Los Angeles and in unincorporated areas of the county. Residents in the neighborhood have called for accountability and asked why some people were still in their homes, despite a door-to-door evacuation order. The Police Department is now requiring a captain to sign off on detonations, in addition to the two bomb technicians and a supervisor who are already required. The incident prompted the Los Angeles Police Department and FBI to review police protocols regarding the detonation of explosives. The bomb technicians overloaded it above the safety rating, however, even as authorities are investigating if the detonation device had a defect. The explosion - which damaged dozens of homes, businesses and vehicles just days before July Fourth - was highly unusual, officials say, because such containment chambers are designed to withhold blasts.
