It was not immediately clear whether Salyer had an attorney.

Authorities say Salyer was arrested Tuesday at John Wayne Airport after security screeners detected suspicious devices in his bag. The bomb squad found artillery fuses, a sting ball grenade, which is an explosive that shoots out rubber projectiles, a small knife, and steroid and Adderall pills.
