Newport Beach Police Department spokesman Evan Sailor said that the unidentified boy had allegedly taken the bomb materials to Horace Ensign Intermediate School, where they were found earlier this week, the Los Angeles Times reported Wednesday.
"He had the equipment to manufacture a type of acid bomb that was not put together but could obviously cause serious injury," Sailor said of the materials found in the student's locker.
The shocking discovery prompted an immediate evacuation of the Newport Beach school on Tuesday and led to the boy's arrest.
Police found the materials following up on a tip from a student that the suspect had been in possession of illegal drugs.
While area parents were immediately concerned for their children's safety, a spokeswoman for the Newport Mesa Unified School District told the Times that the situation was handled appropriately and no students were in danger.
