An Army private was arrested Wednesday for allegedly bringing stolen explosives aboard a United Airlines flight in California. 

Pfc. Christopher Eric Wey, 19, was charged with attempting to carry stolen explosive devices and transporting stolen explosive devices on a flight between Yuma and Los Angeles. 

Wey was arrested at Yuma International Airport Wednesday after a standard screening detected explosives in his luggage. Security found half an ounce of C4 explosive smuggled inside a tobacco can in one of Wey's bags.  

Authorities believe Wey was not planning on using the explosives in a harmful matter and that he stole the C4 while attending an explosive training course. If convicted, Wey faces up to 10 yearsin prison and a $250,000 fine.
