Authorities say a U.S. Army private is in custody after trying to bring a small amount of explosives on board a United Airlines flight from Arizona to Los Angeles.

U.S. Attorney’s spokesman Robbie Sherwood says 19-year-old Pfc. Christopher Eric Wey was detained Wednesday after Transportation Security Administration screeners at the airport in Yuma found about a quarter-ounce of military explosives in his bags.

He was arrested and charged Thursday with attempting to carry an explosive onto an aircraft and transporting a stolen explosive. A criminal complaint alleges that Wey stole the C4 explosive at a recent training course and that there’s no sign he intended to harm anyone.

Sherwood says an attorney was appointed for Wey at an initial court appearance in Yuma, but lawyer’s name wasn’t immediately available.

I’m glad they were able to find a quarter ounce of C-4. Dogs?
