CHICAGO — An explosion at a University of Chicago dorm room has launched a federal investigation. Now, former student, Aram Brunson, is facing charges in a scheme to develop bombs for a militant conflict in Armenia.

Authorities say “the chemicals found in Brunson’s room were consistent with the fabrication of black powder, a type of “energetic material,” used in some ammunition and as a propellant in fireworks, among other things.”

Prosecutors allege Brunson sought to engage in revolutionary direct action and terrorism in support of Armenian causes.

Prosecutors say Brunson made videos of himself teaching others how to make explosive devices and rig doors and desks with grenades. His internet searches also allegedly suggested that he planned to take action against foreign diplomatic facilities in the United States.

The FBI says Brunson moved back to his home in Massachusetts last August.

He was stopped at the Boston airport while heading on a trip overseas, but when TSA found explosive residue on his bag, he was allowed to continue traveling.

He is now believed to be studying at the American University of Armenia.

Brunson is not in custody.

Federal authorities say each of the charges provide for a sentence of up to five years in prison, three years of supervised release and a fine of up to $250,000.
