On Friday evening, Pennsylvania authorities arrested a Russian citizen for reportedly possessing a weapon of mass destruction.

Police arrested Vladislav Miftakhov, a 19-year old who the Altoona Mirror reports is an engineering student at Penn State Altoona, after finding “a suspected bomb and other bomb-making materials inside a suitcase.” They had originally gone to his residence to investigate reports that he was growing marijuana at his home. 

Miftakhov “is charged with possessing a weapon of mass destruction, risking a catastrophe, possession with intent to deliver marijuana, possessing instruments of crime, prohibited offensive weapons, incendiary devices, recklessly endangering another person, possession of controlled substances and possession of drug paraphernalia.”

A bomb squad “safely deconstructed the suspected bomb,” which Miftakhov said was made with materials he purchased over the Internet.
