TULSA, Okla. — A 28-year-old man facing federal charges in a pipe bomb explosion outside an Air Force recruiting center in Oklahoma had been enlisted in that branch of the military and was decorated for his service, a military official said Wednesday.

Oklahoma Air National Guard Capt. Jennifer Proctor told The Associated Press that the suspect, Benjamin Don Roden, enlisted for Air Force active duty in April 2012 and joined the state’s air national guard in October 2014.

Proctor said Roden had been a senior airman whose job involved fire protection, but that he was discharged from the air national guard’s Tulsa-based 138th Fighter Wing in April. She did not provide a reason for his discharge.
