A grand jury has indicted a former Air Force senior airman accused of setting off a pipe bomb outside an Air Force recruiting office in Oklahoma.

Benjamin Roden, 28, now faces a seven-count federal indictment in the July 10 bombing in suburban Tulsa.

Charges against Roden include malicious damage to federal property by use of an explosive and possession of unregistered destructive devices.

No one was hurt in the explosion.

Court records describe Roden as a disgruntled US veteran who ‘hated the military’.

Roden has been detained since his July 11 arrest. A judge ordered Roden to undergo a mental evaluation in July after defense attorneys questioned whether he can assist in his own defense.

A mental competency hearing for Roden is scheduled for August 29.

Roden served in the Air Force at the Whiteman Air Force Base in Missouri and acted as a firefighter, reports Fox 23.

He later joined the 138th Air National Guard Fighter Wing Unit in 2012 and the International National Guard in October 2014 before he was discharged this year.
