Edison Police Chief Thomas Bryan said the teen, who attends Edison High School, had "fewer than six" bombs made out of carbon dioxide cartridges packed with gunpowder and buckshot.
Bryan said the teen had no immediate plans to detonate the devices -- but if he did, they could have been deadly, The (Newark) Star-Ledger said Monday.
"Anything that's stuffed with gunpowder and shrapnel and BBs and has that much force can certainly do a lot of damage," Bryan said. "Think about what happened in Boston. They were pressure cookers and how big are they?"
The teen has been charged with possession of homemade bomb devices and was released to the custody of a relative. He has been temporarily removed from school while administrators look into the matter, officials said.
